Is this a common problem? had pump 2 years having to really keep the ps higher used to keep it on 38 then 55 60 today had to keep it at 70 or even 80 in order to get A decent flow rate how often do change you pump ? Last pump ?

iam running two shurflo ones over 4years old and the other is over 3years old and both are used daily

Filter blocked?

Sorry to hijack but when running my pump yesterday water was not coming out at full flow so i turn the my varistream controller up to 80 then it stopped and flashed PS ,

What does the PS mean

Also when i turn the it down to 30 the pump kicked in again .

My tank was running a bit low and had drawn some air into the pump but it was not that low . Mike

[Dave Willis]

sounds like you are trying to run the pump faster than the pressure setting can cope. Probably need to up the pressure a tad to match the higher flow.

PS means Pressure Switch. The pressure in your system has built up to high levels and the pump pressure switch cuts in to stop the pump.
The controller is reporting what it see,s here and is not activating the pressure switch. Something is causing a high pressure build up in your system, Check for any grit or dirt in the brush head and jets and ensure the hose is not badly twisted or kinked.

Have you changed any fittings or hose recently also did you find the high pressure was happening during very cold temps?
It may be worth recalibrating the controller to take into account the higher pressure in your system.

Hi Crystal it may be a worn pump motor it is also worth checking for any blockages or air in the system. The recent colder temps will also effect your system, Before you change the pump try using the auto calibration.

Hiya thanks , just arrived at work <horrible traffic> unblocking the filter sounds a good start I can see like a bit of sand In there, didn't know that I had to match the ps with the flow so ill try that too, calibration didn't seem to do anything but I didn't try those 2 things yet, I didn't  think the cold would do Anything As I had drained the pump, guess ill check these things before we determine a warn pump motor

Crystal. It 100 percent is the brushes inside mate. I had same issue, replace them and all will be fine, or better still if pump is few years old just replace it.

[Ian Sheppard]

Yes the cold air temp effects the expansion rate of the hose as the hose wall is stiffer in cold weather also odd as it may seem colder water moves slower the nearer to freezing the slower it gets.
These effect the pressure in your system.

[Crystal-clear]

Okay , I played around with the flow thing and its better not great 60ish at least not 80, also I forgot to say I had this sort of poor flow situation when the tank was filled again after the system being drained so maybe air was a Contributing factor too, mick what are brushes sorry I'm just crap at DIY I'm assuming somewhere on the pump lol

[roundbuilder]

Lol yes inside is a brush kit. The brushes are warning you that they are on there last legs as not working surficiantly. All wfp online shops sell them.

Its all very well saying its 100% this or that but you dont know.

Checking the filter will take twenty seconds and could resolve the problem and wouldnt mean replacing the pump.

Now Im not saying its 100% the filter (how can anyone not there possibly tell?) but the check is simple and quick so Id suggest that before ripping your pump to bits (or replacing it!).

[Crystal-clear]

Yea I'm gona check the filter when my water line goes down a tad i can already see tiny bits of grit in there, mick can you link me these brushes :p,  I got a flow jet think its called from Gardiners

Hope that helps.


Ok maybe not 100 percent but highly likely.

[Nick_Thompson]

Mick, dont be bullied! I took 100% as a sign of your enthusiasm. You stick with it man, 100%.  

Your mate Nick.

If it is not the strainer that is blocked then it is likely to be either a split diaphragm or the brushes worn out.

At about £33 for a brush head assembly on a 2 year old pump it is debatable whether it is worth replacing when a new pump is only about twice this price and everything else on it will be new as well. If you take the pump to pieces and find the diaphragm is split then replacing the diaphragm is well worth it at about £18 a pop.

[Crystal-clear]

Cheers what ill most likely do if that's the case is get an another one as I'm crap at DIY so I guess 2 years of use before one of those bits ware is pretty much the norm? If that's the case would be good to know to make sure I've had a decent run

Thanks for the quality reply Ian no dirt or grit it was cold yesterday i do alter my Cal on daily basis sometimes .

Take Monday quite cold so had it set higher,  then yesterday it was really warm at +7 so altered it through the day to maintain the correct flow so as not to waste to much water . Mike
