Clean It Up

I seem to have developed an annoying problem with my pump.
I can't get more than a trickle even when the tap is wide open.
It used to blast out 10ft if I wanted it to.
It's not a connection.
It's not an airlock.
The pump is whizzing along.
I just can't get much pressure. ???
I gave the pump a whack and it flowed a bit faster for a while, but it's slowed down to a trickle again.
The pump didn't sound any different though.
Any ideas?
Oh, and it's a 60psi Flojet.

Air or a strangled inner hose core.
Failing that a weak pump
-
put a short length of hose on the pump outlet and suck it while switching on the pump.

Cheers Dave, at least someone replied!
I've done that actually, and Ian did it today too.
It helped for a few minutes, but it dropped soon after.
Thing is, like I said, the pump sounds fine, it's not slow or labouring.
It's whizzing along. ???

Try it with ians hose reel
-
theres not a small hole in the diagphramis there?. Not too clued up on the insides of the pump but if theres a diaphragm
-
take the bottom of the pump off i think its 4 screws and see if youve got a blockage , when you remove the bottom you will see a rubber seal remove that and you will see if theres any crap inside , allso are you using a strainer as the meshing in the strainer can clog up and cause what you describe , you could allso turn the pressure of the pump up and see if that helps the screw to turn the pressure up is located in the little black box at the bottom of the pump , i think clockwise turning will increase the pressure but just do it half of turn if none of them work for you then i dont no what to suggest mate .
-
Cheers guys, I'll take it apart and look then.
I have got an inline filter, but I cleaned the gauze out in that the other day.

Squeaks,
I reckon this is a good idea. It's just a bit of basic fault finding, but I guess the problem could be in your hose?
-
Don't suppose the jets on your brush are blocked? Try it with no hose reel just a foot of hose from the pump and see if it delivers maybe?
-
I had this for ages, and just couldnt figure it out, til i changed my hozelock fitting on my hose reel, now its like a new pump!!
Just try changing them 1 at a time, from the tank thro to the hose reel, each 1 in turn, they sometimes stick!!

No, there's quite a slow flow when it's just the 2ft piece of hose from the pump outlet.
-
Cheers Mick, I'll check that too. ;)

I've had that on one of my reels before squeaky, its like its half on or leaking air or summat? if you push it on hard the flow may increase then pop off again when you let go.
-
How about a blocked vent in the tank lid? Looks like you may need to borrow a pump from someone to rule that out too?
-
Have you tried running it just out of the hose that connects to the hosereel.

Yes, that's what I meant.
It's not pumping out of there as fast as it should (or so it seems) ???
-
Should have got Ian to try his pump on it.
-
i had a problem with flow, and found it was my pole in the end,
the hose was being pinched when top section was not extended try checking using another :-\
-
connect a bit of hose from a tap to the OUTPUT of the pump
turn the tap on SLOWLEY and not too high
then try it, if no joy, turn the tap up a little more
worth a punt
-
Grrrr!!!! >:(
It was ok for the first 2 hours today, then it slowed to a trickle again.
I took hose off reel connection and sucked the water through.
Then it spluttered for a moment and started to flow ok again.
Worked for 2 houses, then slowed to a trickle again. >:(
Must keep filling itself with air or something... ???
-
How old is the pump?
Sounds to me like the carbon brushes may be wearing in the motor.
You may be able to get a replacement end bell kit from a Flojet supplier if this is the case.

The inline filter maybe letting in air. If possible try it with out the filter and see how it fares.
-
Yes that inline filter was letting air into my system too. I did away with it. I now use a stainless steel tube going into the container, this has it's own filter stuck in the end of it. No problem after this. Dai
-
Cheers, another good idea.
I'll have a look. :)
-
I got rid of all my hoselock fitttings on the inlet side, so now my tank outlet has jubilee clips straight over hose and sureflo connectors on the pump.

here
-
Dave, don't you risk getting crap from the tank blocking the pump?DAI
-
Dai
Forgot to mention , I have filters fitted , but they are screw on type rather than hoselock , will take some pics tommorrow
-
Mine's all connected like that anyway Dave.
The only hoselock fitting is the one to the reel, and the problem is before that.
-
Well, after a complete strip down and finding no leaks or blockages I phoned Alex Gardiner.
His assessment is a damaged diaphragm.
Sounds right, as that would cause a drop in pressure, and also be the reason why my pump isn't shutting off, as it never reaches pressure. :-\
Trouble is, it's bank holiday weekend. :(
God knows how you fit it too. ???
Anyone want a wfp system? ;D
-
No thanks mate they're more trouble than they're worth!
I'll have your van though!
