Sink Drain Plumbing

Fred,

I saw your write up of the replacing the sink drain plumbing.

I did something similar, except used pc instead of abs, and I dropped the size down right off the baskets, rather than before the hose.
I think I like your idea better -- less chance of back up from one basin into the other when draining.

I often use a trick on PVc and abs when it's not under pressure (waste lines, etc.) that I might need to disassemble.  As you know if there's a bunch of short sections and tees, elbows, etc., it's about impossible to cut/remove a section so that you can maybe unscrew a pipe adaptor or something -- you may need to trash the whole assembly and start from scratch.

The trick is that instead of cement, is to hose clamp a joint at a key location (because pvc and abs is an interference fit anyway), using a strong ABA style or T-bolt.  It's amazing how strong and leak-free the joint becomes and impossible to get apart wile clamped.  I have even used this trick w/ industrials application on a manifold under 20 feet of vacuum with no leaks.

Interesting, I haven't tried clamping. I'll try it next time. I usually just friction fit the assembly and ensure I'm right before gluing.
