Shurflo Water Pump Running Constantly (9 Viewers)

[Robgoals]

Hi,

As the title says, water pump keeps running even when taps are off.
There was a few drips from the filter/sieve and some debris in the sieve that looks to have been a seal from somewhere. Tightened up the sieve and no more drips but pump still runs endlessly.
When the taps on I think it looks like air might be getting in somewhere too. Any suggestions about next steps? Do I need to go hunting through all the pipes looking for a leak?

Thanks

Yes on hot side normally.

I assume it wasn't cold enough last night to open the frost valve? I guess you'd have noticed if the water had been dumped?

I would think it's dragging air in on the suction side if you dont have a leak on the pressure side.Try the little filter on the suction side, unscrew the plastic cup to see if there and cracks and make sure the O'ring is ok.

Ok thanks will check that first. Doesn't seem to make any difference if taps on hot or cold in terms of air getting in.

No not cold. We're in Spain so fairly toasty still.

Ok that makes sense. Presumably the thing in the sieve that looked like a chewed up seal came from the suction side. Not obvious where it's from but will try and figure it out.
This is the pump and sieve if it's helpful.

Could the thing in the sieve be it’s own seal breaking up?

Yes possibly. Just had a breakthrough. Tightened up the sieve as much as humanly possible and seems to have temporarily solved the problem. Will look to get a new seal soon.

Yes there is a thin O'Ring that should be seated inside the plastic clear part, it just unscrews. The Oring is orange in the photo.

Here it is on Amazon
