Standpipe Design Question, Washer
Hi, This is my first post to these forums, I've been going nuts trying to find an answer to this question.
But first, let me thank Speedball for posting a part of a plumbing code dealing with cutting and notching load bearing walls. 2 1/8 inch bit through the top plates of an exterior wall mid way between truss. No need to use a strap because of the exception (entire wall structural sheathing) but I probably will because... well... I wear both suspenders and a belt.
Here's the question (and conundrum):
I'm installing a 2" clothes washer drain of PVC in an exterior wall. I bought a washer box but it didn't take long to realize it would be near imposable to fit the trap in the wall and plumb it to the box without a couple of 45s and 90s and some magic getting the vent line to the trap outlet and running the pressure lines. Not to mention being in North Ohio right off of Erie and it gets COLD. I don't want t6o cramp all this into an exterior wall as it could compromise insulation (not much room) and result in freezing.
I'm thinking of running a 32 ~ 34" standpipe through the bottom plate, two wide 90s continuing compromise down (to get around the foundation block) and into a P-Trap, then a vent fitting.
It's the 90s that are causing me a head scratcher. I know sending the water through the two 90s will work, but will it pass inspection? I have been looking for a reference on standpipe 'shape', if it can be 'convoluted' or if the standpipe has to be straight into the trap.
??
Truth is, this is how it's getting plumbed, I need to know if or how much to duck when the inspector see's it.
In days of old I would probably have had no problem finding an answer. I would have gone to the library and looked in a/the code book. Darn time crunch.
Before posting this I scanned 5 pages of subjects and read quite a few threads (back to Aug 13th or so) in this forum. I see lots of problems with new washing machines powerful pumps and draining, suds back ups and other stuff. All of which I wish to avoid.
You see, this is my Mother in Laws new kitchen/laundry addition, I can't afford to screw this up.
