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!
