Hi all, ive been trying to get uncle johnny contact number too but no one has sent me yet. My kitchen sink piping was leaking and couldnt get uncle johnny contact so I used the guy I got last time for my toilet when I couldnt get uncle johnny number also. Was not bad. For those who know the hdb standard cupboard door in the kitchen to hide the waste pipe. The long one. When I renovated my kitchen I boxed it up. Happen to be the water pipe coming to the sink was through that cupboard and leaking from inside. So had no access to it. I thought must break open already, my new cabinet gone. Then he think think for a while then trace the pipe all. Then he say no need. He say remove the top of the cabinet where hollow and cut the pipe going along the ceiling and down and bypass through my cabinet, behind my oven. I thought not bad, good idea. He say thats the best option. Save on e carpentry. I thought cannot do will hit my oven and if drill the cupboard will be ugly and crack but he say sure can. So I thought no other better idea so say do la. In the end he did. All done nicely. He take the things in e cupboard and the oven do all nicely and clean up. The drilling was also good. Not too big and never crack. In all was good on my wallet and lucky he did as he talk. Just sharing with all. If you have e same prob can use this idea. Save alot. I have pics if anyone wants.
