So I finally got the new Surflo working without it cycling too much...
I turneed the pressure switch in a bit.

New problem noticed, big one.

It seems MEGA powerful compared to the old pump, even though they are both 60psi.

I can't really turn the tap down enough, and then the pressure is blowing open all the connections and soaking me.
Even my hoselock connection to the reel is now leaking and getting the van wet.

Is there a way to turn the output down?
This is why I went from a 100psi originally to a 60psi.

This one is more like 500psi.

A pump speed controller would be useful. Try using a brass female hoselock fitting on the reel make sure its the ones with the metal ball bearings inside to hold it in place rather than plastic it wont leak. You can also unscrew the clamp that normally holds it to the hose and put a jubilee on instead. Jubilees for all other connections..

I never needed one before, how come I do now?

Squeeky,

If you don't use a controller, you need a bypass back to the tank with a valve in it so you can direct the excess water back to the tank.

Fit a bypass, all you need to do is, put a T piece each side of the pump. And a piece of hose from each of the T pieces, the cut the new piece of hose and put a flow control tap in the pipe.

because a flojet and a shurflo are different, should have stuck with the flojets, they dont need a flow controller when you use it with 6mm microbore,

[SherwoodCleaningSe]

By the sounds of it the pressure switch is up too high.  To solve the problem you'll either have to.

Turn the pressure switch down.  This will solve the hoselocks popping off but may cause the pump to cycle when in use.

Fit a bypass valve.  The pump will be working all the time as soon as you switch it on.

Get a varistream.  These have annoying little habits of their own but if set up correctly will stop the pressure build up.  If the flowrate is a little high then you could get away with an ecoflow, but if not then the ecoflow will be no use as it works off of the pressure switch.

Fit something else after the pump to take up the extra pressure, like more hose or a DI vessel.  Bit pointless but works.

You could of course just find better fittings like O rings.  But you might need the flexibility of hose locks.

It is down to the flow rate , even though they are both 60 psi , one could deliver 2 ltrs a min and the other 6 ltres min.

You could eithe fit a bypass hose or get an electronic flow controller, which will give you variable speeds.

I wouldn`t mess about with T peices just buy a Eco-flo or Varistream.

[Sir Squeaky]

It's not messing about when one is about a tenner and the other is over £100.

Got to do what I can afford.

[NWH]

I`m only thinking of you,you have complete control over your flo-rate with a flo controller.

[Sir Squeaky]

I can control my flow rate fine with the inline tap, that's how I've always done it.

I don't want to spend lots of money to do the same thing.

Can't the pump just be turned down?

[NWH]

Crikey Discount when are you going to fit that lot in your van,i couldn`t stand my van being as untidy as that lol.

[NWH]

I thought it was a picture of your van after a crash lol.

[Clive McDonald]

Alex sometimes has some brainiac answer to problems like this Squeaky so I guess he's your last chance. But from some of the other posts I don't think it's a problem that can be solved easily unless the pressure switch can be tweaked.

If it's any consolation I have three varistream and pumps and still get cycling etc at times.

[Wayne Thomas]

I've stopped using Shureflo pumps and switched back to a Flojet pump, (with the pressure switch left connected up on the pump) and connected to a variable setting flow controller with an on/off switch.
Varitech built it and I fitted it in my van. It regulates the pressure of the pump, whereas varistreams regulate the amperage. Much simpler and the flow is up to 7.6l a minute if I want.
I've more than enough water now and not a hope in hell of keeping up with it speedwise to clean windows unless I keep the flow turned down low.. My setting would normally be on between 12 noon and 1pm on the varistream, now I'm on 10 oclock with this new flow controller and that's plenty of water to keep up with.
It should be good for cladding work though with the setting turned up really high.

[NWH]

If i put my varistream on 1 o`clock it`s to much water,your setup is different to mine that`s for sure.I you using loads of hose or something.

[Wayne Thomas]

100m 8mm minibore. I don't like holding a pole any longer than I need to when it comes to cleaning windows otherwise it gets boring having to wait for water just to clean a window and I get impatient, lol

[NWH]

I use a good flo rate but on my system that would be to much water.

[Wayne Thomas]

I used 630 litres of water today and I wasn't wasting my water. Just cracking on cleaning windows, lots and lots of them.
