late 50’s house, solid floor, is this a gas or water pipe, how can I tell.
Thank you,
how can I tell
Have you cleaned it ? By the way the pipe is crooked in the fitting it's gas - classic work from 50's gas board Nothing like the Gas Safe tech. guys today
So this is defiantly not water?
Ok it’s under a concrete floor so not easy, it has the letter C stamped on the elbow. I’ve tried running the cold tap, it’s silent.
It's more likely to be an old gas pipe and as Nige mentioned the pipe is cross threaded and looking at the amount of threads in the elbow it would be pi$$ing water but hold gas.
You could try this, warm it up with a gas torch then get someone to open up all the cold taps, the temperature will drop quickly if it's the cold water pipe,
then do the same with the hot taps the temperature will rise.
You never mentioned it was coming from the street in your earlier post, just warm the pipe up and it will cool down quick with cold water running through it if it's a water pipe,This would be the feed in from the street (water) so why would it rise. Yes cross threaded!!! Why would it leak water not gas?
Thank you..
