Can I Use Pex For Tub Spout

Long story short it is unacceptable.

Can i use pex for tub spout.

Pax has a smaller inside diameter than copper when you will turn on the spout your showerhead will also be dripping if you read the manufacture instructions it will say do not use pex for spout level 2. After investigating the 3 4 will work just fine no restrictions. These spouts will work with just a clean open copper pipe as it has a set screw adapter to clamp the pipe. 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. 2nd reason pex is flexible and the spout relies on the pipe for support. Pex when you pull up on the diverter the entire spout moves. Pex to tub spout.

2 reasons i learned. The interior diameter of pex is actually a fraction smaller than copper this forces water to come out of the shower at the same time as the tub spout. 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. There is no way to secure pex adequately to keep a tub spout from flopping around.

Copper is the only professional installation material. 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. Copper keeps the spout in place.
