This shower was installed when the house was built in 2004. I have no paperwork of any kind. Through many hours of web browsing and talking with Delta, I found that I have a Delta Moniter series 1700 shower faucet. It is leaking at a pretty good clip. Delta is sending me replacement parts. Any tips on taking the valve apart to get at the rubber and springs they are sending? And help will be appreciated.
Usually the Delta shower valves havea chrome 'bonnet' that needs to be unscrewed to get at the 'guts'. After a few years it is usually stuck on pretty good. The bonnet is what the handle lever inserts into. Be very careful because you have to exert a lot of force to get these loose usually.
I'd spray it liberally for a couple days with a good penetrating lubricant like 'pipe-break' before trying to unscrew. Protect the chrome and maybe tap it several times with a rubber mallet and keep you fingers crossed. Counterclockwise, obviously. Try not to overtorque so as to damage the supple lines.
