tacky p-trap installation
After carefully choosing the design of my new powder room, my plumber made my hard work useless (see pic). I purchased this Kohler modern p-trap to keep my powder room looking clean and contemporary
. Instead the plumber used a trap adaptor that looks atrocious.
Please tell me there is a better way to install my p-trap.

No room for P-trap!
Comments (7)a p trap can be twisted into lots of shapes; it doesn't have to run in a straight plane.... just saying this in case it is not clear... 2. then , even with a full size trap (which can take on any shape), the plumber has the option under Code to run the sink drain over horizontally to somewhere towards the wall and then drop the drain down to the trap. This is in other words two tight radius elbows in the drain line, the first one right under the sink tailpiece and the second one above the ptrap. 3. he can also offset with two 45 degree turns (called one eighth bends) 4. any combination of the above is permissible too. 5. offset drains are made in one piece if you wish to have that too. The key words to search on are Tubular double-offset or just "offset drain" . Executive Summary: you do not need any other P trap. The standard P trap works when you re-route the drain line to fit your space no matter how tight the space is. -david...See MoreReplacing Unvented Drum Trap with P-Trap and AAV
Comments (2)Under the IPC & IRC the maximum length of a fixture arm can be computed by dividing the diameter of the drain by the pitch. If an 1-1/2" line is installed with the code standard 1/4" per foot pitch the maximum lenght would be 1.5 / .25 = 6ft but in this instance the line has a 1/2" pitch so the maximum allowable length would be 1.5 / .5 = 3'. (The bottom of the drain line at the trap weir may not be higher than the top of the line at the vent opening). Both the configurations illustrated above would not pass code for a number of reasons. The simple solution would be to remove the drum trap & extend the length of the tub drain tailpiece. Code will allow up to 24" vertical drop from the tub drain opening to the water level in the trap. Attach a P-trap and run the line with a 1/4" per foot pitch. A wye can be installed on the drain line with the side input angling downstream. You can then put a street 1/8bend on the wye side opening input, which would turn the side opening vertical and attach an AAV where the base of the AAV is 4" above the drain line. REF-IPC 917.4 Location. The air admittance valve shall be located a minimum of 4 inches (102 mm) above the horizontal branch drain or fixture drain being vented The air admittance valve shall be located within the maximum developed length permitted for the vent. The air admittance valve shall be installed a minimum of 6 inches (152 mm) above insulation materials....See MoreP-trap or S-Trap?
Comments (2)From the US Inspect website: The full "S" trap or 3/4 "S" trap should not be used in plumbing installations. These traps are almost impossible to vent properly. The 3/4 "SÂ trap forms a perfect siphon. The problem with "S" traps is that the waste water may siphon out, causing the trap to lose its liquid seal. Every plumbing fixture, such as sinks, tubs and showers, should have a proper trap. Toilet traps are built into the bowl of the toilet. If a sink, etc. does not have a trap, trace the drain for other inequities that may be present (i.e. draining into a sump pump, a dry well or to the exterior surface). In older construction, there are thousands of "S" traps in use. Older building codes did not address this issue. In many cases it will be very difficult to change an "S" trap to a "P" trap. Can you install a studor vent to alleviate this problem?...See MoreLooking for thoughts on installing a P trap with a built in clean out.

6 months agoThanks to all of the responses to my post. Just for clarification this was both a remodel and a new job. This powder room was once a laundry closet. Due to a rotting floor discovered during an encapsulation, we decided to turn our half bath and a closet into a laundry room and the laundry closet into a powder room. The walls and most of the flooring was stripped down to the studs to re-route the plumbing and flooring. The plumber ran the plumbing for the toilet and wall sink.
Kohler has responded and I have received these great comments from my fellow Houzz followers. I only need to know that this can be fixed. If not I have wasted $225 for the p-trap and will purchasing another brass p-trap whether it is a bottle trap or the classic to make it right.
According to the plumber, Rutherford county, Tennessee is okay with either.

6 months agolast modified: 6 months agoIf you are going to do the fancy bottle trap, you really need to have all the brass fittings and the perfectly placed shut off valves in the satin brass finish and rigid supply lines, not the standard flex lines and chrome valves.
When you put in something fancy that it meant to be an exposed focal point, everything about the installation needs to be brought up to this level because it's meant to be noticed.
If you just had all the standard equipment under there, nobody would look at it, it's meant to be ignored and it's what people are used to seeing.
But once you put something that is meant to be seen and noticed, everything is going to be seen.
So you can either waste the $225 bottle trap and try to sell it maybe, or spend a couple thousand dollars buying reinstalling everything to make it all look like something like this is supposed to.
I'm not saying this to criticize you, I frequently set up these situations where if I do X, then Y and Z have to be done as well or it just looks halfassed.
