Be careful about restricting the flow as this could overwork the over pressure switch. In my experience most pumps that fail prematurely have a knackered op switch because the owner was too tight to buy a flow control.
If your pump fails disconnect the 2 wires to the op switch and join them together. In most cases your pump will magically start working. only it won't cut out if you close the output hose. Seems obvious to me but judging on the number of pumps I have sold where buyers had this problem it isn't obvious to everybody.

Just wondered if anyone can help. Bought the wcw backpack and broke the control numpty of and now stuck on the fastest speed emptys in no time. Soon as i saw the control numpty and how it protrudes i thought i must be careful i dont snap it off, anyway it happened lol. A bad design i think, only a few months old but obviously my fault.

Mines done the same m8 after a week. Cost me £22 to replace flow switch.
Going to put a kitchen cupboard handle over it to act as a bumper . (seen speed switches on e bay for £3 for model railways does anyone have any idea if these work for back packs,)

When you use your backpack do you add hose to it or just make sure you have a long pole hose?

i use pole hose from pole to backpack works fine.

ws18 from john hewitt £110 delivered been using it a month great backpack.

[ps outthere]

I bought an ESR505c from John Hewitt. It has an intermittent fault that John can't find or repair.
I would not recommend for this reason + wasted postage return fees and, it still cuts out and won't work for hours.

Wish id bought another shurflo now to be honest started off with it about 3 years ago still going strong. Just thought the wcw one had a handle and a easy flow controller which snapped off far too easy. So now no flow controller  at all. I have a van mount but take son with me sometimes with the backpack which is now the 3 year old shurflow. you just know that control on the wcw backpack is going to snap off, too late now though.

[gary999]

i would never buy another shurflo, pcb goes far too easy
on them and they are way overpriced.

i have a couple of ws15 never have a problem with
them well priced they have a decent 70 psi pump
that chucks out 2.6ltr per min and are cheap to replace
if and when needed

do you mean if you use a tap on the pole turning it off to stop the water can damage the pump.?
