No, I need the non return valve too. well, gonna try it and see if it solves pump problem but I wont hold my breath. Google it but cant find where they sell it.Something like this?
What is the issue you're trying to resolve?just ordered one, should fit ok, they are 1/2 inch and the hose coming out of tank is standard garden hose so fingers crossed.
I meant to get one ages ago, hopefully it will stop or help stop airlocks. Am still getting trouble with pump not working right. Also am gonna put the pump as low as it will go. I know some have the pump up high though without any problems so maybe not worth it. Just trying everything really. Got new battery, needed one anyway, but that wasnt the issue, everythings tightened up etc. If I dont get any joy soon im just gonna get a fleet of backpacks, and take arms against a sea of dirty windows! sorry, got a bit carried away thereWhat is the issue you're trying to resolve?
Handy, my mates always saving chain saws etc that people think have had it. will have a look in pump at wkend if the other efforts fail.Check the strainer see if it is blocked
Or
Take pump head off (which is the black plastic housing) wash out the inside, there is a centre rubber cone /disc. take a small screwdriver and slide it under under cone and gentle lift it up. Have a look to see if there are any bits of dirt or resin beads that have got under the rubber cone. Once cleaned WELL (take you time, even if it looks clean) and you may well find it has resolved the issue. Screw it all back together turn pump on full bore / 99 or 10 and the water should start flowing through. Have had this many times over the years on my vans. Always fixed the problem, been out to vans of workers and window cleaner friends and sorted them out at the side of the road. After figuring this out a few years ago i got some of my redundant old pumps that i believed to be broken, did the above and they all came back to life. I only use the Shurflo Pumps This is the centre cone i was taking about
yes they look ok, metal too and good price.https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F332904828044
Have used these before with no issues.?
Hi i'm just about to fit one of these non return valves did you fit before or after pump or doesn't it matter where it's fitted? ThanksI bought 1 from Varitech (streamline). It's been fitted and working perfectly since the start of the winter. It's cut into 1/2 inch hose. I can't remember the price as I was stocking up on filters, resin and other spares at the time. It wouldn't have been expensive.
Hi is this fitted before or after pump? thankshttps://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F332904828044

Yeh mines just a cheap nylon/plastic one. I put it about six inches after the tank outlet. Dont know if its done much or if thats what my problem was but no airlocks anymore and cant do any harm at that price.If it's any help, I fitted a non return valve about six inches above the tank outlet. My theory being to hold as much water as possible in the system above the nrv. My nrv is nylon but I expect the result should be the same. No airlocks since fitting. Touch wood. All my problems prior to fitting the nrv were down to air being sucked in on the suction side, before the pump. The tiniest amount can cause havoc.
Great thanks i will fit this nrv before pump and hopefully same as you no airlocks. Thanks for your help.If it's any help, I fitted a non return valve about six inches above the tank outlet.

That's great will do the same with mine. ThanksYeh mines just a cheap nylon/plastic one. I put it about six inches after the tank outlet. Dont know if its done much or if thats what my problem was but no airlocks anymore and cant do any harm at that price.
Yeh also put the pump as low as possible if you can. Some say doesnt need to, but Im sure it helped stop airlocks for me.Great thanks i will fit this nrv before pump and hopefully same as you no airlocks. Thanks for your help.
