Elongated drain trap

[msteger]

I ran into this drain today under a bathroom sink. I would imagine problems down the road, such as early deterioration of the pipe due to prolonged water presence in the trap and horizontal arm plus the level the water has to reach downstream from the trap. Suggestions?

I wouldn't be worried about the pipes deteriorating, but most of the fittings are bass-ackward at best (the hozizontal "tail-piece" behind the sprayer nozzle for instance).

Suggestions? Have the whole mess re-plumbed by someone who can read instructions.

Yeah, you are right.. some of these fittings are going the wrong way. Funny... I looked at it and said to myself 'what the hell?' and that is not even looking at the direction of some of the fittings. The seller was a self proclaimed "general contractor" (that about says it all, alot of the time, eh?) and I found all sorts of other plumbing and electrical issues in the home, including a wood stove that had wood paneled walls right next to it that were red hot to the touch and insulation installed over knob and tube wiring.

How about:

P3201.2 Trap seals and trap seal protection.

Traps shall have a liquid seal not less than 2 inches (51 mm) and not more than 4 inches (102 mm).

Exception:

Traps for floor drains shall be fitted with a trap primer or shall be of the deep seal design.

Tom, what do they mean by 'trap seal'? The height of pipes entering or exiting the trap? If so, is the measurement taken from the bottom of the trap?

[Tom Corrigan]

The trap seal would be the distance vertically from the weir of the trap to the top of the pipe at the bottom of the "U".

The water below the top of the "U" provides no seal, and the water can't rise above the weir. It looks like the seal depth in your picture is much more than 4".

Matthew,

This might help.
