That is what is called a 8 trap, Are you sure he was not making moonshine

[Harry E. McClard]

Gee. I'm still trying to figure out how they did that and have it look so neat; also trying to name it... 8 Trap sounds ok, but maybe something more technical like an Inverted SPS8 Trap or something like that?

Sps8 trap is good Maybe we can forward it to joe the plumber

Symmetry aside, it's an S-trap. Write it up.

I was always told that if there are 4 or more inches between the discharge side of the trap and the drain line that it is no longer an "S" trap and subject to the self siphoning problem. I remember a thread on this not to long ago where something similar was discussed. I don't have a current plumbing code book handy to look it up. Maybe someone can find the acutal measurement requirements.

Well i would not think it could siphon , but i would write up as sub standard plumping practice But great art work

[Michael Larson]

S traps often do function but they are not permitted by code because of the potential for siphoning and loosing the trap seal.

I see no evidence from the posted photo that the fixture is properly vented.

I see plenty of S traps that have been that way for 50 years.

I simply make the client aware of the possible problem and that they were common at one time.

They can decide if they want it fixed.

I have been this way for 53 Years I still work.
Well maybe not like I Used too but But with a little sweet talk i get there lol

[Jack L. Gilleland]

I give it an 8 on the creativity scale and a 10 for neatness. But it still is not done in a professional manner. The supplies have been leaking long enough to rust and Michael's right about no evidence of a vent, unless it is vented off the branch within 3' of the fixture.
