I hope I provide enough details/information so that I can get some good feedback. And yes, I have googled til I'm blue, but don't come up with what I'm looking for.
Problem dates back to a water softener. Some how the catalytic beads in the shower escaped into the water system. The softener is long gone and replaced.
Afterwards, problems began in the water heater. Constant replacing elements and low output. We finally replaced the water heater, but noticed a sludge buildup in the water heater that leads me to think the bead and their resultant sludge breakdown was the problem in the water heater.
About that same time as the water softener episode, the shower faucets exhibited a marked reduction in pressure. I've cleaned screens, and the casual things that one can do. The water pressure in all other areas of the house are good and high. Volume and pressure is good in all other faucets.
I haven't called a plumber in yet, because I think I can remedy this by getting to and changing the seats/springs. I think, based on what I saw in the water heater connections that I have particulate impeding flow. I HAVE gone to my plumber supply and gotten parts list and parts breakdown.
My question here, is how to remove the stem, and guts to get to the seat and springs on the temperature side. I have a link to photos. The volume side is a no brainer, it has an euschutcheon. It's the temperature side that I'm curious as to how it comes out. My plumbing supply is ordering pretty much everything inside on the temperature side, and just seats and springs on the volume side.
Once again, any advice on how to remove the temperature guts will be certainly appreciated. Here's the link to plumbing photos. (copy and paste)
