Encountering a new issue with one of my vacu flush heads...these are 18 yr old units that I've maintained since 2007. Recently one of the heads has lost a great deal of suction. It still clears but without the aggressive suction as normal
I have changed the bowl seal..replaced the piston / plunger on the low profile vacum unit. I changed the duck valves about 6 months ago. This unit has had a issue of losing vacum ...in addition the pump would not shut down so I would turn it off at the breaker which is close to the head so it wasn't a big issue , but now with the inability of the unit to gain suitable suction regardless how long it runs is a issue. I'm getting no water loss in bowel so I know it's not the bowel seal. Also looking at the amp meter it is only pulling about 4 amps.as it pumps abou half of my other unit...any ideas Peggy?
