Hi Guy's

Need a little advice on my pump, 100psi surflo with varistream.
One day last week it took me ages to get it primed, I noticed it sucking air through one of the quick fit connectors, now I used these on the pump so I could remove it and bring it in every night.

Today I removed the quick fit and connected the in-put of the pump direct to the filter/tank, Switched on my pump and again it took ages for it to prime, any ideas why its doing this. I have an in-line filter from the tank to the pump, my hose's are the clear type and can't see any air bubbles.
there is water in the filter, and when I disconnect the filter after the tank and before the pump, water flows easily by gravity.
Any help would be gratefully recieved.

I had a similar problem ages ago and found that if i turned the Varistream up too full and opened the tap on the hose, within a few minutes i had a good flow again.
I do this each time i change my resin.
Not had a problem since.

Cheers Craig

This is what I did put it on full blast, but still takes ages to prime, Just wondered what Is causing it all of a sudden. Last week fine, then friday this happened, There has to be an explanation for it.

What sort of connector have you from the pump to the hose?

I was using one of the connectors that stop the flow once you un-coupled it.
I found this didn't help the flow.
Changed it to an ordinary connector and it improved

Thats the type I had, but now I don't have any connectors to my pump input side. and its still playing up???

Or are you on about the out-put side, I still have the connectors there.

[craig jwc]

Yes i mean the output side. Sorry should have said

[jeff1]

Yes i mean the output side. Sorry should have said

So If I change my quick fit on that side to a normal one, you recon this will help??

[craig jwc]

I found it made a difference.

If you have an inline-filter before your pump check that isn't blocked

Thanks Craig

I'll change the fitting tomorrow, and check out the filter again, but the water flows freely from the filter. But will check it out again to be certain.
Many thanks for your help.

No Craig, I only bought my wfp gear just before christmas.
and fully started wfp, the begining of this month, so the pump hasn't been going that long.

Hi Guy's

Need a little advice on my pump, 100psi shurflo with varistream.
One day last week it took me ages to get it primed, I noticed it sucking air through one of the quick fit connectors, now I used these on the pump so I could remove it and bring it in every night.

Today I removed the quick fit and connected the in-put of the pump direct to the filter/tank, Switched on my pump and again it took ages for it to prime, any ideas why its doing this. I have an in-line filter from the tank to the pump, my hose's are the clear type and can't see any air bubbles.

Hi Jeff, i had a similar problem when i first got my shurflo pump, it wouldn't prime and i had to suck it through to get it started, i also had a in-line filter before the inlet of the pump but this didn't stop the smallest strands of plastic getting through and it resulted in my valves in the pump being smashed. ( seems a lot of people have this problem with little strands of plastic being left in the tank )

It costs around £15 to replace the valves if i remember.

Hope this is not your problem and it's something more simpler.

Kind regards

 This is what I have just done.

Went to the cold damp shed  First thing I did was a volt and ammeter, and hydrometer test on my battery, that is perfect.

Next I stick my suck end into my barrel and turn on pump,(full blast) left it for over ten minutes and nothing, so I sucked  on the out-put and eventually after a few more minutes got it going. I left it running for 30 mins and it was pumping fine?
I then switched off the pump and with the pipe still below the surface switched it on and off about a dozen times, and it continued to work?
Raised the in-put out of the water, until the tone of the motor changed, now were sucking air again, took ages to get it going again, So I went to my workshop and got myself a non return valve and fitted this, every time I took it out of the water and re-dipped it in, worked every time, I'm not leaving this valve in, I want a pump that works, I understand we can get problems with wfp equipment, but this pump is only about 6 weeks old.

What do you guy's make of my findings?? and what do you think I should do??

I sometimes get this problem. I disconnect the outlet pipe before it gets to the hose reel. Once the water flows I connect to the hose reel and then it's fine.
I don't use in line filters any more. I have stainless tubes that go into the containers,
These have strainers built into the end. You could make your own strainers out of plastic scouring pads. Just stick a bit in the end of the tube. My in line filter was a constant source of airlocks. Dai
