I'm a new homeowner trying to replace a shower diverter. Not a plumber, so forgive any incorrect terms.
I have a female 1/2 inch connector inside the wall about 2 1/4 deep from the tub wall. The builders used a non-standard(?) 6.5inch PVC pipe going from that connector to a screw on type diverter. The old diverter is hopelessly clogged with deposits.
I'd like to replace this setup with an all metal option. Basically afraid of the PVC pipe breaking at the metal connection point, and flooding the inside of our walls. There's also an optional decorative spout ring, but preferred since there's some minor wall damage.
Option 1
- Find a 6.75 inch brass nipple. (6.75 since the decorative ring adds .25in to the length of the diverter.)
Option 2
- 4-ish inches of brass nipple to get out of the wall, then a PVC slip connector and glue the rest of the way to the end of the diverter.
- Nice since I can control the size of the PVC with a slip connector and PVC glue
- But here's the pipe length confusion part - how do I know how much PVC to add? How many turns of the spout are good?
Option 3
- Use existing PVC pipe, since oddly 6.5in PVC can't be bought new at my local stores. Also no decorative ring. The current setup lasted this long...
Option 4 - anything you can suggest. Copper tube is not an option, since the hole to access inside the wall in barely 1.25 in wide.
