the valves are pricey but you can either get a valve rebuild kit or a toilet rebuild kit for 100-150 bucks

i have had my microphors off and changed some o rings and it wasnt all that hard. i think i could get one off in 15 minutes or less and most everything is easy to get at inside.

seems like it shouldnt crack the housing at 100psi, but rather blow the seals out. but i dont know for sure
