Yes they do work ok , but you will get through a bit of water if you have no way of controling the flow , you will need one of these on your hose to sort this

Tolwoods,

I think you have four options:

1.  No flow control.

2.  A varistream.

3.   A flow restrictor (such as is shown in P & F's picture above).

4.  A flow restrictor with a pump bypass.

Using no flow control will mean that you will pump water out at a huge rate of knots.  My 60 psi shurflo will emit 7 litres per minute, when I think 2 litres is enough for me.  If I had a 650 litre van-mounted system, then this wouldn't be a problem.

A varistream, from the posts I've read here, seems to be the best option.  I haven't a clue how to fit one though.

A flow restrictor will reduce your water output, but it may also damage your pump, since your pump is attempting to take more water in, than what it's pushing out.  When I attempted to restrict my pump with a ball valve I found it 'cycled' (it pulsed and didn't sound very healthy and my water jetted on and off; like a heart beat).

A flow restrictor with a pump by pass works, if you can do it.  I've seen a comercially produced one (Peter Fogwills) and that worked fine.  My poor attempt was useless; but if you're good at DIY stuff, this may be a good option; especially if you're on a budget.

E-Mail Matt (that's his user name) and he'll show you how to do this.

I hope this helps.

I have a return to tank valve fitted on my van mount , this saves me the need for the varistream .

Any water that isnt used or wanted simply flows back to tank .
