I have an Einhell constant pressure pump (with bladder) that I got from the big green shed a few years ago. It works great, but every 3 months or so it starts to short-cycle, as in the pump kicks in about 2 or 3 pulses per second, rather than continuously pumping. It should maintain pressure in the bladder, use that first, then re-pressurise it back to 40psi when it drops to 20psi.
pump prior to bleeding, notice the pressure gauge is still at 40psi
I am worried it will burn out. The previous pump we had actually caught fire, luckily I was home and quickly connected the burning smell and "why doesn't the toilet flush".
The only remedy I've found so far is to close off the tank supply, drain out the pump then re-prime it and start it up again. When doing this I notice the following:
- a lot of pressure in the pump, I have to open the bleed valve very slowly otherwise it'll explode in my face (learned the hard way).
- I connect a bike pump to the air valve after bleeding, it sounds like the air bag is compacted as I can hear it crumpling as it expands.
- No matter how much air I pump in, the pressure gauge remains at 0.
What could be the cause of this, is there a leak somewhere that's causing it to drop pressure? Time to scrap it and buy a new one? I've tried contacting Einhell support a few times but I've never got a reply.
Thanks
