Three Inch Plumbing Stacks Capped At The Roof For 16 Years


I went to estimate a roof today. I noticed out of the eight PVC plumbing vents 2 of them (the three inch) were capped. There are two three inch as mentioned. Four two inch , And one 1 1/2 inch. none of those were capped. Were these left on for a waste pressure test perhaps? The homeowner didn't mention any odd waste behavior except he said for clogs occasionally during the winter. No gurgling or siphoning. And its a regular over the pipe cap not one of them inside pipe test or temporary caps. its a very steep roof as well. 10/12

The smaller lines are probably for sinks and the other small fixtures, the large are probably stack and or toilet vents and toilets will work just fine without being vented.

I only said what they are for because you seemed to think they would have noticed they had a problem. Where the capped ones lower than the open ones?

And until you know, it's best to leave them alone. Chances are, these were for some future use and opening them would cause water damage inside. Or, the house could have been remodeled and it was easier to leave the stacks in place and cap them. Unless there are unvented fixtures, you wouldn't want to disturb the status quo.

Re: Three Inch Plumbing Stacks Capped At The Roof For 16 Years


They are higher up the roof than any of the other stacks. The owner is original and I asked him if he remodeled. He never remodeled and theres no abandoned plumbing in the house. None of his neighbors have caps. neighboring homes have similar stack placements without caps. Not my job to fix something that ain't broke. They aren't filters because i was up on the roof today and they are your usual solid 3 inch PVC caps. The owner thought they were couplings open at the top. Hope I can get the roofing boots over them without tearing the rubber but they should go.

Wipe some vegetable oil on the opening of the rubber flashing and on the edge of the PVC cap and it should slide over.

It may be possible that the fixtures meant to utilize these vents are using the drainage piping from other bathroom groups as a wet vent. If they are able to draw enough air from the rest of the system then the fixtures would perform properly. The system doesn't care where the air comes from just as long as it gets it.

Re: Three Inch Plumbing Stacks Capped At The Roof For 16 Years


Ok contracted and completed that roof. left the vent caps as they were of course. Went to another roof for an estimate down the street. And climbing all over the roof what do I see? Another capped three inch stack. All the 1 1/2s and 2 inch stacks are open. I guess I couldn't see the caps from the ground when I was at the other house.

Re: Three Inch Plumbing Stacks Capped At The Roof For 16 Years


Sounds like the original plumber did a partial rough for the second floor bath to be. He plumbed both homes ,and maybe more. Later ,another plumber complets the bath ,having no clue what clever Harvey did!. They need to know
this possible senerio. A plumber needs to check it out. Bad time to be on a 10/12 in New Jersey. You could assist plumber on roof maybe. You would score big points in that hood!

My Kmart sneaker soles were worn and it was a bi**h climbing around on those loose tabs. Earlier in the day I had a couple near slips on the roof i was supervising. I doubt the plumber did a tree in advance of a future potential upgrade. These are not custom homes. these are seventeen year old builder grade tract houses with trusses on two foot centers and three tab sentinel roofs that are starting to blow off. The sidings cheap the doors are cheap.

No they paid me for the (1st) roof which is done already. Still working on the 3 inch stack cap mystery. Maybe i should call the plumbing inspector for that town.

only caps I have seen on roof vents is a test cap for air testing the drain lines. they are usually removed after the inspection.
