Can I Use Pex For Tub Spout

Copper is the only professional installation material.

Can i use pex for tub spout.

Long story short it is unacceptable. With a built in diverter you could use a pex drop eared ninety degree female adapter and a nipple but that is more trouble than it is worth. There is no way to secure pex adequately to keep a tub spout from flopping around. The tub spout can be copper brass or galvanized pipe.

When pex is used on those tub spouts the excessive back pressure sends water up the shower. After investigating the 3 4 will work just fine no restrictions. Pex when you pull up on the diverter the entire spout moves. Soldering to the nipple with the pex attached is not optimum but can be managed if you have room to tightly wrap a water saturated cotton rag around the copper and extended over the pex portion.

2 reasons i learned. Copper keeps the spout in place. You cannot use pex because the pipe coming out of the valve needs to be able to support the weight of the tub spout and handle the abuse of pulling pushing down of the divirter built into the spout. Ironranger mn i m pretty sure what they meant was that if you use 1 2 pex you could have a restriction since it s smaller than copper.

These spouts will work with just a clean open copper pipe as it has a set screw adapter to clamp the pipe. It is only created on tub spouts where a diverter closes off the easier path out the tub spout to send it to the shower. 2nd reason pex is flexible and the spout relies on the pipe for support.
