I stopped by RS this morning, bought a bunch of drain plumbing parts. The first part, one connection from Ace cost $4, the RS parts to connect 4 sinks with a trap cost $3.96. We’ll need 5 more thread nut connectors and more bushings plus one or 2 flanged tubes from RS. The drain system is looking good, spent the evening piecing it together, even came with the right bushing to fit the smaller hand sink, cool. It’ll need trimming to fit the right lengths, but we have the parts, shorter is easy. We’ll use a flex hose to join the hand sink to the mains and trap with hose clamps. A drain system for $8 bucks, maybe a little more, but what a deal, ReStore, too cool.
