A Step-by-Step Guide to Swapping Out a Delta Bathtub Spout
Installing a Delta tub spout varies based on the wall plumbing: iron pipe, slip-on, or copper pipe. Each type has its own specific steps and tools.
By Hayden Hayes
Bathtub spouts direct water downward into a tub.
Delta offers a range of styles and finishes for three distinct tub spout types, each corresponding to the plumbing configuration behind the bathroom wall: iron pipe, slip-on, and copper pipe. The installation method differs accordingly.
Iron Pipe Installation
Step 1
Insert a large flat screwdriver into the opening at the bottom of the existing spout. Rotate the spout counterclockwise to detach it from the iron pipe.
Step 2
Remove any old Teflon tape from the pipe nipple threads. Wrap new Teflon tape clockwise around the threads three times, pressing it firmly into the grooves.
Step 3
Thread the new Delta spout onto the pipe by turning it clockwise. Cover the spout with a towel and use adjustable pliers to tighten it further until it sits flush against the wall with the opening pointing down into the tub.
Slip-On Installation
Step 1
Use a hex wrench in the opening underneath the spout. Turn it counterclockwise to loosen and remove the screw.
Step 2
With both hands and moderate force, pull the old spout away from the tub wall. Discard it.
Step 3
Slide the Delta spout onto the copper pipe until it contacts the wall. Insert the new hex screw into the bottom opening.
Step 4
Attach a hex wrench to the screw and turn clockwise to tighten it completely.
Copper Pipe Installation
Step 1
Put a large screwdriver into the spout's opening. Rotate counterclockwise to unscrew and remove the old spout, then discard it.
Step 2
Using adjustable pliers, pull the O-ring off the copper pipe and set it aside.
Step 3
Solder the tub spout adapter from the spout kit onto the copper tube protruding from the wall.
Step 4
With a hacksaw, cut off the excess tube just in front of the O-ring groove.
Step 5
Slide the new O-ring from the spout kit into the O-ring groove at the end of the brass adapter.
Step 6
Thread the Delta spout onto the pipe near the wall by turning it clockwise until it is hand-tight and rests against the wall with the opening facing down into the tub.
