Things You'll Need
Delta is brand name of both bathroom and kitchen fixtures manufactured by the Delta Faucet Co. Delta tub faucets are usually equipped with an attachment that has a tapered edge so they can be fitted to a water pipe. This attachment can be screwed onto the spout as well. It is possible to install a Delta tub faucet with a few tools without hiring a professional plumber.
Slip-on Faucet Installation
Push the new Delta faucet over the pipe connected to the plumbing in the wall. The pipe should be protruding from the wall.
Hold the tub faucet in place with one hand against the wall once you have it fitted over the pipe.
Slide the set screw into the opening in the base of the spout and secure the screw with an Allen wrench.
Screw-on Faucet Installation
Examine the wall pipe and figure out if you need to add the rear-mount attachment to the tub faucet. This faucet is made for the plumbing pipe to connect to the front.
Slide the end that does not have tapered edges into the faucet. Hand-tighten the attachment into the faucet spout; the O-ring on the attachment will prevent leaks.
Wind the end of your plumbing pipe with three layers of plumber's tape. Attach the Delta tub spout to the pipe and hand-tighten in a clockwise direction until the spout is tight.
Cover the spout with a cloth to prevent damage. Finish tightening the spout with a pipe wrench.
