Took a bit of thinking to determine the use of this precious master piece.
It is located in the utility room closet as you can see in the pic with the WH, the 2" PVC line travels thru the wall to the left side of the pic and terminates about 1’ above the garage floor. The house has a slab floor and I just assumed there is a trap in the line below the slab but no real way to determine this.
Any ideas what this marvelous piece of plumbing is used for as I have my own ideas lets see if great minds think alike:mrgreen:
Wow. Crap. That is a brain buster. Nice one Charley.
I can’t get my head around it. It can’t be for solids unless its for draining an RV tank which has a grinder and a pump to drive stuff up that slope. That slope makes no sense whatsoever…
Maybe a strange method of venting the plumbing system?
Oooo, maybe it’s a way to prevent or redirect a backup or overflow which is continually happening in one section of the plumbing. Seems like they could also be draining something into it by removing the cap and the 2 inch line would allow whatever they’re draining to overflow without flooding the house.
Bob I do know what its for had to think about it for a while, it has nothing to do with the WH just happens to be located in the same closet. No sump pump installed anywhere. Yes you are correct I don’t ask many question on this MB I can usually reason out what something is or is used for, after 50 years in the work force there has been a bit of water under my bridge.
Your radon thought was the first thing that entered my mind also but I included the (WTF) is this. Has nothing to do with radon;-)
My clues should have given it away but I understand your suspicious thinking???
Utility room What is the major appliance in a utility room that requires a plumbing drain ??? !!! A washing machine , second clue **home built in 1977 !!! what was the diameter of the washing machine stand pipe in 1977 construction codes ??? !!! 1-1/2" walah home owner moves in with a brand new washing machine that requires a 2" drain line to properly drain and immediately overflows owner calls a plumber and his cheap A fix was to install a secondary stand pipe large enough to accommodate the new machine and just in case it also might over flow he installs a 2" drain to the garage floor from the secondary stand pipe. BTW the secondary stand pipe was connected to a existing floor drain near the WH which is also improper due to the trap beneath the slab for the floor drain is not considered a wet trap and allows sewer gas into the garage area.
Bobbie do you not have old 1-1/2 inch washing machine stand pipes in your Yankee area or have you just been ignoring them as they can be a problem with new washing machines
