Absolutely I replaced the seats as well. I remember well, because I didn't do it with the first try, because I couldn't find the right wrench here. My tools all seem to walk away... Assumed that was the cause, went back to the store for the wrench, replaced the seat and found no improvement.
Figured the stem might be wrong for the diverter valve somehow though it didn't make sense it all looked like the same sizes as before. Went back to Home Depot and got a fresh set. No change.
Decided it must me some problem with the design of the parts. Tried a different brand from Lowes. No change. I cannot see how it could not work, but it obviously does not.
Replacing the valve is gonna be a challenging situation because of the tile wall, and this is the only tub in the house and one of only two showers. Without going into excessive details, one of the kids is not gonna deal with not using this particular bathroom while the wall gets torn apart and repaired, nor to I have a ton of time or money to do that. (If the water were leaking into the wall, that would be another matter.)
Clearly Im no plumbing expert, but I cannot see a danger in adding a diverter to the spout. Am I wrong?
Isnt all those diverter spouts usually do to divert the water up through a second attached pipe to a shower head? I had always just assumed that without a conventional diverter valve, gravity made water stay out of the shower unless the diverter spout blocked the lower exit. Is there more going on there?
If Im right, then if the original diverter is set in the middle, the diverter spout would be doing the same thing, except the shower might have slightly reduced volume of flow, but then again, then this was built it was to carry a lot more water than now needed to the shower. This shower head is a modern low-flow, while the old tub faucet is carrying enough volume to charge a small fire hose.
Besides, the old diverter wont fully divert to begin with, so that would mean even less pressure could build up on the spouts diverter.
