Installing Shutoff valves & Supply TubesBy: Justin Beaumont(Not liable for use of information)

Planning (2 - 3 Hours)

● Make a supply list.○ suggested: compression valve, compressions fittings, flexible supply

tube.

● Tool list: Mini-pipe tubing cutter or minihacksaw, emery cloth, two adjustable wrenches.

● Carefully inspect the pipes under your sink and determine whether they unscrew from the wall or if they will need to be cut.○ If you need to cut the pipes off of the wall make certain that you DO

NOT cut close to the wall.

Disconnect Old Pipes (15 - 25 min)

● TURN OFF THE MAIN WATER SUPPLY!

● Unscrew the supply pipe at the wall under the sink.● If the pipe is soldered in place, you will have to cut the

pipe with a mini-pipe tubing cutter.○ Only use a hack saw as a last resort.

Disconnect continued...NOTE: Make sure to leave enough room between the plate (escutcheon plate) and the cut to install the new fitting.

● Use an emery cloth to deburr the pipe.

Begin Installing New Fixtures● Place the compression ring over the end of the supply

pipe.○ Make sure that the ring completely

covers the end of the pipe.

● Thread the compression valveinto the compression nut.● Make sure that the valve slides

squarely & snuggly over the ring.● Use your hand to tighten, use a drop

oil on the threads if the nut won't turn.

● Don't use pipe compount on acompression fixture.

Tightening● Do NOT over tighten the

compression valve to the nut.

● Use one wrench to hold back the valve while keeping it square anduse the other wrench to turn the

nut.

Supply tubes● Follow the same procedure as valve installation, in

order to install the water supply lines.

● Make sure that you briefly turn on the water to flush the lines previous to installing all new fixtures.(Note: Be smart and place a bucket under the plumbing to catch the water)
