Shurflo Pump Spares (1 Viewer)

[TheTwoOfUs]

I knew I was tempting fate by saying we hadn't had any problems with our motorhome. Just got back from Hawes where the ShurFlo pump has developed a leak between the pump halves. I believe that complete heads are available but does anyone have a recommendation for a supplier please?

sometimes you can just tighten the screws. the service kit is pretty expensive

From experience, its probably cheaper to replace the entire pump in the long run.

Is it 20 or 30 psi?

I agree, after several attempts to repair diaphragm pumps I have come to the conclusion that its not worth the effort, if it leaks or doesn't move enough water or won't shut off just replace it.

Did mine 2 years ago.new diaphragm .old one didn't have a gasket between joints.new kit came with gasket.not had any problems.Cost 18 pound's.got mine from leisure shop.com

When ours had a little leak it was just because calcium deposits had formed in the joint and allowed a small leak path.

Strip the head down gave everything a good scrub and rebuild, I put a bit of Vaseline around the diaphragm/head joint and job was a good un and still is, that's the second one I have done as we had the same in the caravan.

Before buying anything.. As big1 said...

I'd remove the pump housing, clean it out and provided there is no visible cracking or damage to the diaphram, reassemble adding a smear of Vasaline to the diaphragm sealing edge... it's important to tighten the screws equally and not too tight..

EDIT

just saw @funflair post.. great minds

Change ours from 20psi to 30psi because the old one lost performance as the toilet was not flushing all the way around the rim now with the 30psi loads better

You have to be careful increasing the PSI rating of a water pump. The PSI rating is often matched to the specific boiler/water heater fitted to the vehicle i.e. in our van, 20 PSI for the Alde 3000 boiler.

Yes and the push fit plumbing is a risk, you can bet it will fail in the most arshole of a place to get to!! Worthwhile checking the spec from the boiler as Canopus has identified.

I concur with all the warnings about increasing the pressure of a system. My working life was spent designing hydraulic systems so I know the problems involved when increasing the pressure without due regard to the designed working pressure, even at these very low pressures.
