Old Pipes Leaking
Remodeling a kitchen. Put new base cabinet in for sink, had to remove both water shutoffs to get into cabinet bottom. Put same ones back on. Turn water main back on, and now the pipes are leaking. Not where I put shutoffs on but down in basement where 10" length of pipe goes through floor. There are no unions or anything and yes I did check the shutoffs again. Is it possible that both of these galvanized pipes have cracked now? Leak only where they are in the floor which is wood and very tight. Also the pipes even have wear marks when we pushed one down to check the leak. Is this possible and will this keep happening down the line when we start replacing with new pipe to repair the leaks? Any tips would be appreciated and thank you ahead of time.
Thanks for the help. I just wanted to post an update. The pipes where all replaced a day after the problem. The reason for the leak was the old wood floor was so tight around the pipes that it had prevented the pipes from leaking. The house is 1940 built. So over the years the pipes actually had wear marks from the floor in them. You could actually see where the wood had made it's mark. The pipes where cracked in both spots in the floor. When we moved the pipes is when we broke the seal, but you could see where they have been blackening the hardwood floor for some time over the years with water. Just enough not to be noticed, until we moved them out of the floor. The pipes actually had to be cut an knocked out with a sledge hammer that's how tight they were. Thanks again and I am just posting this for the informative reasoning of why they leaked after I touched them to install new base cabinets.
