How to build a (relatively) cheap Dental Water Jet aka oral irrigator, similar to a Waterpik or Interplak. Great for cleaning between teeth & braces or getting rid of tonsilloliths (tonsil stones).

Step 1: Parts List

What you will need for this build:
(Clockwise from left in first photo)
Inflation needle $1.48 in kit of 3 @ Wal-Mart
Hose Adapter 3/4" FH x 1/2" FIP $4.76 @ Lowe's
Male Pipe to FIP Hex Bushing 1/2" x 1/4" $2.59 @ Lowe's
1/8"x1/4" Hose Barb to MIP adapter $2.77 @ Lowe's
Thread Seal Tape $0.97 @ Lowe's
Clear Vinyl Tubing 1/4" od x 1/8" id $1.96 for 20' @ Lowe's
Hose Connector Adapter (see 2nd pic) $3.19 @ Lowe's

Step 2: Some Assembly Req'd

Now put everything together:

Put Seal Tape on all threads to prevent leaks.

Screw the bushing into the hose adapter
Srew the barb into the bushing
Cut desired length of tubing (I used about 3') and insert barb into one end
Use a knife to taper the outside of the other end so that it will fit into the inflation needle
Screw the inflation needle onto the tubing
Wrap the needled & tubing generously with tape to prevent leaking
Wrap the needle up to the hole on the side to prevent water from shooting out in two directions.
Replace your faucet's standard aerator with the hose adapter aerator
Screw Jet Assembly onto faucet
Turn water on LOW

Better yet, buy a replacement waterpik handle (like $12) and then you have a faucet powered waterpik! They have an oral irrigator you can attach to faucet on amazon with switch to direct water as well.

i don't know about constantly reconnecting the adapter to use the faucet, but this would def be a great project for a two sink bathroom

Pictures could be a bit better, but the idea is nice.
