Gotcha with that title, eh? It's really much simpler. Before I begin, the desired response from you is, "GLUE IT." I'm ready to do just that, but as yet another idiot check, I'm hoping my potential booboo will be acceptable... The question is, is using 1-1/4 PVC for galley drain piping rather than the HH 'code' of 1-1/2 something I won't regret? Can't imagine for my meager uses it will make *any* difference, but I only now learned that the larger is 'code'. I know, I know, I should read the entire 20,000 page construction industry's code before even attempting this project. ;) So, take it all back before I start, or glue it? | ||

Duh...what's the difference between PVC and HH? | ||

1 1/2" pipe.....when you buy a 1 1/2 'p'trap for the lav. it will come with a 1 1/4 adapter if I understand your question... | ||

Scuze me - I have purchased 1-1/4 pvc & boatloads of L's, T's, unions, etc. for going from sink to underfloor and all the way to the grey tank. My badly formed question was, should I take it all back and restart with 1 1/2 instead, or GLUE IT UP with the 1 1/4 I already have? I'm hoping the 1 1/4 will be just fine and dandy. Tell me I'm OK as is. (HH= HouseHold/Sticks&Bricks) | ||

Chuck: Indeedy, 1-1/2" is code for residential (HH), as you know. HH kitchen sinks often have disposals and dishwashers plumbed into them, so this might explain the diameter requirements. I agree with the others that 1-1/4" is more than sufficient for RV uses, since you're not going to want to put a lot of scraps and goo into your gray tanks. Also, I'd ignore the 1/4" per foot slope requirement and make your RV gray plumbing MORE sloped, because a small out-of-level condition can make your spent water need to flow UPhill to the tank... and that just won't happen.

Gary, 1-1/4" is a bastard size. Most kitchens are plumbed with 2" for obvious reasons. Baths are plumbed with 1-1/2" and sink traps are sized likewise. If you can get a straight cleanout in that pipe clear to the HT, proceed, otherwise, don't waste the time. Get the real stuff. Michael | ||

Lotta RVs use 1-1/4". I went with 1-1/2" in the bus. The nice thing about 1-1/2" is you can find the fittings easily anywhere. 1-1/4" is kinda funky. If it is just a matter of going back to the store to swap it all out, I'd go with the 1-1/2" stuff. Scott | ||

got one more suggestion.....run all the drain lines first....they all need to run downhill,the pressue lines can go anywhere | ||

I have never seen 2" in my life. Kitchens are 1-1/2, Bath is 1-1/4. I'm pretty sure many RVs and Marine applications use 1-1/4 tailpieces for the galley (But there is no P-Trap in marine) Just as a sanity check, I just looked in the kitchen and bath in the house I'm living in. 1.5 in the kitchen, 1.25 in the bath, same as my recollection Gary | ||

I would hold that slope to 1/2" per foot because you will almost always be well within that amount from level. I would stay with 1 1/4" because there will often not be enough flushwater to keep the drain clear. Larger drains take more water to keep clear. For what it's worth.

Some of it is curing as I write this. Sometimes in an effort to spend more time working on the bus than I do wrestling to get *any* information at Home Depot I start grabbing what looks right before having all the information I need. Usually I overstudy the issue to death before taking any action and that leads to a snail's progress. Iiick, my girlfriends have said I need to be more spontaneous and look what happens when I do! Thank you yet again for your ongoing reassurance. Looks like I can squeak by again. I won't be so haphazard with elec., I promise. And FBB, see all the fun you're missing with that pre-built RV? | ||

The plastic pipe comes in many thicknesses, from really thin crap that drains doubble sinks to series 80 that uses threads instead of glue. Glued is fine , as its so cheap you can "Doctor" (burry) all your mistakes. I found that the series 40 is heavy enough to take the occasional ding from a hot water heater instalation or the canning pressure cooker learning flying. Strong doesn't cost more than very thin, only place you will prefer 2 inch is for vent lines that get thru the roof. Bigger size seems to help with interior smells. Additionally we have found an insink garbage disposal to be very worthwhile. Those fresh shrimp skins will stink by morning in a simple trash bin (even a good covered one) but seem to never be a hassle ground and washed into the combined black , grey tank. Works for me, FAST FRED | ||

I would like to clarify that Schedule 80 pipe may also be glued, and contend that solvent-joined pipe is every bit as adequate, if not more so, than threaded. ABS and PVC solvents do not "glue" pipe in the traditional sense, but literally fuse the two surfaces (pipe and fitting) together. When done properly with the proper prep., primer (for PVC) and solvent, along with the "bottoming out and quarter turn shuffle", said joint will be permanent and leak proof. They use this stuff in pressure applications, as well. A leaking solvent joint just means its wasn't done properly and should never be repaired with epoxy or "goo". Just redo the joint. Also, DON'T mix ABS (black) pipe and PVC (white) pipe and fittings. DON'T use a multi-type solvent. Make sure all your waste and vent plumbing and fittings are stamped "dwv" (drain/waste/vent) and that it's properly supported along its entire run. Check out a book from the library on HH plumbing to learn when to use a tee vs. a wye and pay close attention to venting and cleanout requirements. FBB | ||

I wholeheartly agree with FF on the built in garbage disposal. They really work great to get rid of all the food articles that can draw ants or other critters. Also, I found the instant hot water dispenser very convenient. Uses very little electricity to keep the water hot and always available for a quick "spot o tea" or a cup of hot chocolate. Richard | ||

Fast Fred, If you don't have a combination black/grey tank, does a sink with a disposal go into the black or grey tank? | ||

Geez, do we have to tell you everything? The disposal output goes into a secondary cutoff pipe which is plumbed into a large black kettle which contains a collection of fishguts, shrimp rinds and steak gristle. When at the right quantity, place over stovetop and... dinner's ready! | ||
