N.A.

One side of my swing driveway automatic gate stop working last year February time. The repair man said the motor was spoiled and it was repaired. After that only about 6 months, it had problem again. First, the same side cannot be fully opened. No it can be only opened a little bit. Every time, I need to manually push it to open fully. I called the vendor Lam International who provided the gate and did the repair last time. They told me to get repair again but with only 2 month warranty. Somehow I believe that it will be spoil again soon after repairing it Do I have to repair and pay about $250 every half a year for the gate? Should I change the motor to new one? Will it be better that I will not need to repair it for at least 5 years? Should I change the only spoiled side or whole system? The gate including iron and wood is still in very good condition. Thanks for your help!

Just an update for the problem. I have managed to solve the leaking problem. The problem is caused by the PVC discharge or overflow pipe from the water heater. When the water heater has problem or Temperature or Pressure spoil, there will be hot water coming from the water heater and poured to the discharge pipe. In my home, the PVC discharge pipe is buried to the corner of my bathroom wall. It causes the wall very wet after shower. I see some of the water heater installation photos and they also have PVC discharge pipe buried to the wall. Please take a note that it may cause your wall wet. Some of you may believe that the discharge pipe is connected to the floor drainage. I did a test that it does. But it doesn't totally connect, meaning that there is a air gap between the PVC pipe somewhere in the wall. After I changed water heater, the wall is dry now. It saved me thousand of dollars quoted by some plumbers.

The only thing I can think of is that the storage water heater in Singapore is normally small one such as 50L the largest. It is not as dangerous as those in other country which can be 150 to 300L typically. This reminds me something of used battery disposal. I was wondering that there is no good way to dispose battery in Singapore. While in some other country you cannot throw battery just to dustbin. Later I read that Singapore markets carry only those safe for easy disposal (such as to dustbin) types of batteries. If this is the case, I feel very relieved. But you still should have to have a overflow pipe connecting to the T & P valve. I know hot water will power down if the T & P valve is spoil or tank is spoil somewhere. How come some of the installations do not have the pipes?

I see, you mean that the installer don't join overflow or discharge pipe to the T & P valve in Joven because he think it is very safe? The T & P valve and overflow pipe is very important in other country such as US. They have very specific requirements on how to install it from the government. But it seems not the case in Singapore. What is the real reason?

If you have a storage water heater installed in your home, can you share with us how it is installed?

I have been looking into Temperature and Pressure Relief (T & P) Valve and the linked overflow or discharge pipe recently. I have water leaking in one of my bathrooms and I suspect that it is due to water from water heater (Ariston brand) goes into the overflow pipe. I have another bathroom where it has a Joven 50water heater installed. I read very carefully in the label on the Joven water heater:" a). The water heater should not be operated without a Pressure Relief Valve". b). The valve and pressure relief pipe must not be sealed or blocked " But looking at the installation, the relief pipe with red plastic cover goes to the floor of the bathroom. Is ti blocked? I understand that to block T & P valve is very dangerous. No I always turn off my water heater immediately after I used it. I also look at the other installation I can find here: This one seems has no relief or overflow pipe connect to it. The heater is installed in the ceiling, is it dangerous if the water heater is spoil and the water gushing form the T & P valve? These two look right with the relief pipes go into the wall. But look carefully at the second one, the relief valve is turned a bit at the right. Is it block? This one has no relief pipe despite the warnings. Does anybody know how the relief pipe should be properly installed?

How about their furniture in the apartment if you enter the house and they refuse to move out?

The reason the plumber insisting the other pipes are leaking is that the PVC discharge pipe from the water heater will never leak. I wonder if a qualified plumber in Singapore needs to go through proper training on water heater and installation.

I hope I can do that. But the house is a new house and it has beautiful marble wall for the bathroom. I can understand why the developer buried the pipe in the wall, because if it is not buried, it will be exposed and the bathroom will look very ugly. But, the problem is that, if the wall is wet, plumber says that the other pipes are leaking, not the water heater discharge pipe. They want to do big job to fix it. How can we know exactly who is leaking?

Hi, hope you still read the forum. My Ariston water heater is also installed in the false ceiling. Can you tell me how your pipes are going around? Mine has the discharge pipe that linked to the T & P safety valve buried in the wall. If it is leaking the wall will be wet. I don't know if this is a reasonable way of doing such thing.

How do you know this is the water heater leaking not the other pipes leaking. I also have water leakage in my wall recently, I suspect it is the Ariston 50L water heater. It is 5 years old. But the plumber says it is normal hot and cold pipes. I see the leaking point in the wall is the point where there is a PVC pipe buried and it is linked up to the water heater installed int the bath room ceiling. See the thread for details. http://www.renotalk.com/forum/index.php?sh...mp;#entry580806 Is your water heater has discharge PVC pipe open to the air?

What is CU pipe? There are hot, cold copper pipe, T & P valve discharge pipe attached to the water heater. What is the CU pipe and where is it attached to the water heater?

Hi Warrior88, Another support that T & P discharge PVC pipe should not go into drain hole. "Once siphoning occurs, the liquid (be it dirty water, household chemicals, oil, etc.) will be drawn back into the water heater tank, thereby contaminating the household drinking water supply". If PVC discharge pipe terminate at the drain hole, if your drain hole is choked and full with dirty water, your water heater tank will be contaminated. About the T &P valve: "A safety device called a temperature and pressure relief (T&P or TPR) valve, is normally fitted on the top of the water heater to dump water if the temperature or pressure becomes too high." Thus, if there is water coming out of the T & P discharge PVC pipe, there is problem with the water heater (You are right, it may not be in the T & P valve). It is either in too high pressure or too high temperature that your water heater generates. Another possibility is that the T & P valve is spoil (loose or damaged). If the discharge PVC pipe terminates near the wall and filled with gushing water from the water tank due to too high pressure or temperature, the wall will be wet, isn't it even if there is no pressure? If there is water continuously dripping from the PVC pipe near wall, the wall near it will be wet isn't it? Thanks!

Hi Warrior88, Yes, the drainage pipe is not going outside the building. For most water heaters they are are installed on the floor of a bathroom, the PVC discharge pipe is simply lay in the bathroom floor I think. That's why sometime, you discover a pool of water from the discharge pipe in your bathroom floor. I don't think the discharge pipe is end to the drainage hole. In this case you will never find your water heater has problem in the T & P valve. But in my case, the water heater is installed in the ceiling and the PVC discharge pipe is buried in the wall. If the discharge pipe cannot go to drainage, it must be opened inside the wall. When water heater has problem, the wall is wet. I hope it makes sense. Because if this make sense, it explains why there is sudden gushing of water around the PVC discharge pipe sometime. Thanks!

Hi Warrior88, I just found a document about how to terminate a PVC discharge pipe. I asked many people, they all told me that it should go to the drain hole. But it is not the case after I read the following. I think it is a pretty good information for us to understand how the PVC drain is build in a house. http://www.dallascityhall.com/pdf/Building...rgePanDrain.pdf "The outlet of a pressure relief valve, temperature relief valve or combination thereof, shall not be directly connected to the drainage system. The discharge from the relief valve shall be piped full size separately to the floor, to the outside of the building or to an indirect waste receptor located inside the building. The discharge shall be installed in a manner that does not cause personal injury or property damage and that is readily observable by the building occupants." And some from the forums: "The instructions that came with the water heater says to leave a 6" air gap between the temperature and pressure pipe and the floor drain." "Be aware that, if the T&P valve should ever be called on to do what it is intended to do, what comes out of the pipe is a tremendous blast of boiling water and steam. Whether it goes into the pan first or directly on the floor would not matter much. The six inches is intended to ensure that the heater be vented as rapidly and safely as possible, and also to minimize any possibility that the water in the heater could ever be contaminated by drain or ground water."

I just paint it when I see small cracks. Normally it will be gone after applying one to three times of paint. I noticed that the cracks normally happen near somewhere that the wall is drilled such as light on and off switches.

Hi Warrior88, I turned off the cold water inlet to the water heater in the ceiling that near the water heater. My problem is that if it is the water heater overflow problem, even if I install new conceal pipe to mixer, the PVC pipe still will be overflow with water and the wall is still wet. But you are saying the PVC goes to the main drain hole. I just wondering, if PVC pipe really goes to the floor drain hole. If this is the case, when your water heater has problem and the water is overflow to your PVC pipe, you will never notice it. Should it be better that it is terminated some where in the wall so that when there is overflow problem in the water heater, the wall will be wet and you will know that the water heater need to be fixed?

Hi Warrior88, Thank you very much for your reply? Can you explain "If leaks from the PVC, you will only see patches of water trace marks. PVC is dripping water, but for PVC, you see pool of water". Do you mix PVC and copper pipe somewhere here? I guess you mean the last PVC the copper pipes. In the corner of the wall, one side has copper pipe and PVC pipes berried parallelly. The copper pipe didn't go down to the bottom of the wall, but turn 90 degree to the left part of the wall. The PVC pipe goes down to the wall. We didn't hack the bottom part of the wall, thus we don't know how far the PVC pipe goes. I turn off the water heater outlet these days. The wall is still wet in the lower part of the wall where the pipes (copper pipes and PVC pipe) are berried. But int he other side of the wall, it gets much drier.

Hi, Thank you for your reply! I wonder if you can see from the picture I attached. The hacked wall is marked by green line. This is the photo before hacking: Initially, the lower part of the wall surface and the floor is very wet, we need to wipe out water constantly. There were three times, the bathroom floor around the corner had water gushing out. But after few days. The floor is no longer wet, only the lower part of the wall in the two sides of the corner of the wall are wet. The gushing water has never happened again. In one side of the wall, where the copper pipes and the PVC pipe are berried, the wet surface is like a curve marked by green line. In the another side of the wall around corner, the wet is a bit straight line.

Hi, I hope someone can shed some light for me for what the possible causes. The plumbers are asking for $2500 to rewire pipes and the worse thing is that the pipes will be exposed in the bathroom wall. They refuse to think about the possibility due to water heater problem. My water heater is Ariston 5 years old.

One the corners of the wall between my bedroom and bathroom has water leakage. The plumber hacked part of the wall that exposes the copper pipes of hot and cold water. It also exposes a white PVC pipe that is connected to the T & P valve of a water heater in the bathroom ceiling (see the attached image) that is used for discharge of overflow water from water heater. The copper pipes turn 90 degree to the left. The PVC pipe goes down to the bottom of the corner of the wall. The leakage is around the corner of the bottom two sides of the wall and the bedroom floor. The plumber insists that the water is from the two copper pipes. But after hacking the wall that exposed the pipes, the pipes are very dry on the exposed part. He said that if there is leakage, the water will drip down from the pipes, but there is no water dripping after waiting for two days. But he still wants to carry out the work to cut the copper pipes, hack the wall to the top of the ceiling and build a new pair to connect to the top part of the pipes in the ceiling. I have called another plumbers, they did a quick check and said, PVC pipe cannot be leaking, water heater has no problem. They want to cut all the pipes and build new sets that are exposed inside the bathroom. I am wondering if all this is caused due to water heater overflow. Because, when first time the leaking happened, it has huge amount of water fill the floor of the bathroom near the corner of the PVC pipe after we shower. This happened three times, but now it is gone. If it is copper pipe leaking, it shouldn't have such huge amount of water gushing out. My question is: [1]. How does discharge pipe ends? Does it normally end in the main drainage in the bathroom or it simply end at the the corner of the wall such that when overflow water goes to the pipe, it goes to the floor of the bathroom? I am worried if the problem lays in the PVC pipe, it can be done with changing water heater or fixed the water heater overflow problem instead of hacking the wall and build new sets of pipes. Looking forward to hearing any suggestions!

From the image, you can see the gap between the wall and the awning. It is quite big.

Thank you all for sharing! This is the picture to share:

I have a window that I installed a polycarbonate awning on top of it recently. It is leaking between the contact of the wall and the polycarbonate. The contractor uses silicon gel to bond the gap between the polycarbonate sheet and the wall. The contractor told me he will apply more silicon gel on it. I am wondering how this part should be done in order to avoid leakage. It seems not quite right to me that there is gap between the polycarbonate sheet and the wall. Does he need to cut the wall to fit the polycarbonate in a bit or is there any other ways to fill up the gap.
