I bought a countertop dishwasher. Home Depot did not have adapters to connect my faucet to the included quick-connect adapter. I have also heard that the hoses in pull-out faucets are not meant to withstand full line pressure as done by this blog post.
So I want to install a tee on the hot water line and connect that to the dishwasher. Here's what I have to work with:
- Hot water pipe: 3/8" compression (male)
- Dishwasher input: thread OD 26.33mm (1.037"), 4 threads per 7.28mm (0.287", 14 TPI). I think this is 3/4" MIP/NPS.
- A hose that connects to dishwasher and terminates with a nut (14.48mm/0.57" ID) and washer. This matches a male end on the quick-connect adapter which is 15.4mm (.607") OD, 7 threads in 10.16mm (0.4"). I am not sure whether this is M16x1.5mm, 5/8"-18TPI, or something else.
I would like to re-use the hose but don't know what it terminates in. So without that, here's what I've got using hardware store parts:
wall: 3/8" Compression male 3/8" compression tee 3/8" compression supply line 3/8" compression to 3/4" MIP (NPT) adapter 3/4" FIP (NPT) coupling dishwasher input: 3/4" MIP wall==> >══╦══> >==================< <==> >==< <====dishwasher 3/8 comp v 3/8" comp hose 3/8 comp to 3/4 MIP 3/4 FIP coupling 3/4" MIP 3/8 comp tee v to sink hose
This is a lot of parts and brass adds up quick. How can I reduce part count? I tried looking for e.g. a 3/8" comp to 3/4" FIP hose, but even McMaster-Carr only has 3/8" comp to 1/2" FIP. Do they make 3/8" comp to 3/4" FIP bushings? This guy with an identical-looking dishwasher spent $90, which I do not want to do.
