How long have you had it?We just installed a new Jobe Topez 3/4 High Temp valve for our hot water SS bay tank. Well worth the cost. The tank never overflows and the valve always opens.
Is it possible the larger 1" pipe size flows at a lower velocity (With Higher Volume) so it's easier on the diaphragm?I've had much better luck with the 1" Walters than the 1/2? or 3/4" ones, kind of surprising since I would have thought the larger diaphragm would be a weak point. I usually get a year out of a diaphragm in the self serve, at least five in the auto since it doesn't open and close as much.
IMO it's the opening/closing that wears out the seal. I've seen very high failure rate whenever the valve didn't have a drop hose to prevent cascading which makes it open and close while filling. The 1" used to have a much longer rod which also made it need to open less frequently.Is it possible the larger 1" pipe size flows at a lower velocity (With Higher Volume) so it's easier on the diaphragm?
I keep telling everyone THERE JUNK/CRAP!!, it'll fail gave it a couple of weeks.I see on the forum posts that some of the Hudson valves are failing.. How often are these happening - over pre-longed periods? We just installed one at our HP tank so far so good.. but now you guys have me nervous with premature failure thoughts...
Good point....I have a 1" PVC pipe dropped to the bottom of the tank with a tee on it to diffuse the water. Before I added the pipe, it looked like a "Wave Pool" inside the tank. I bet that's what wreaks havoc on the diaphragm....IMO it's the opening/closing that wears out the seal.

Mine lasted about 3 months. Naturaly it happened as things got busy in December.I see on the forum posts that some of the Hudson valves are failing..

Are the floor standing tanks bigger than the ones built onto the stand? It's been my thought for some time that the valve opening and closing more often is what causes most of the wear on the diaphragm seal.I think having the water storage tank mounted on the pump stand is a big factor in quick failures of valves. I have both stand and floor mounted tanks. The valves in the floor mounted tanks last much longer, probably due to much less vibration. I use mostly Walters, and have a couple of Jobe valves that I am trying.

Mep, I have one large (50gal ?) floor tank that feeds a Cat 3535. I remember replacing that float twice in 20 years. I have several smaller (20-30 gal) tanks, both stand & floor mounted for Automatic & Self service pumps. The pump stands valves have to be replaced more often.Are the floor standing tanks bigger than the ones built onto the stand?
