So I’m likely to sell my house but I found some water damage and had to replace some stuff....anyways water was trickling down the bathtub lip that sits between the cement board. A tile lay here and it was just an extremely wet cover-up. Lead to water coming up through my tile. I bought the house this way but didn’t realize the tile wasn’t sealed up in that space underneath! Grr. Anyways tile was put over vinyl which was put over linoleum. I need to continue this later but a leak may be from the shower valves. Any plumbers or someone savvy here? I get water coming out of those valves, it’s a pretty steady stream too. Could this be reason for leak?
Hmm. I got nothing right now, but I'll give this a bump for you. Do you have any other pictures? Pics of the shower valves especially would help. What brand of valves? They can be repaired with new internals sometimes.
I actually ended up buying brand new valves. Having looked up a YouTube video about it it just said to replace them. Hopefully I did it the right way but they weren’t spouting out water where the O rings are between the rod. Need to get a new thing of cement board to replace on the wall and another piece of the plastic wall shield. Gone brittle.
there was is a foolish code that you could not run copper pipe through dry wall or cement board- so you ended up with copper to steel nipples just behind the wall- after many years galvanic action between the two metals rots them out same thing happens with steel pipes into brass valves, takes a little longer though. For what ever reason I woke up one night to a strange sound- like a water fall- actually it was a gusher on the hot water side the 40 psi blew the rotted pipes apart and I spent the rest of the night mopping up both on the main floor and the basement after shutting off the water supply until the shops opened so I could get repair parts. In the process of repairing the hot side I bumped the cold side and it literally disintegrated. Hate plumbing always seems to take a minimum of 3 trips to store for repairs. Additionally my last home had heavy wall copper pipes ( they do not sell that at the stores now days ) and of course the new stuff is thin wall - nothing fits all special order.
Thing is now that brass pieces are there, brass has the better ability to be replaced rather than steel which is ridiculously hard to replace, to the point where the only option is to actually cut and rethread pipe if anything is stuck. I got lucky but I also lost count to how many times I’ve been to the hardware stores now. Always something else. The good thing about the cement board today made for this application is that it is incredibly light now. Allows for more complete drying and don’t need 3 people to stand it up.
