Hi i know that this subject has been done to death but here goes.
Pump flow has been going down for a little while now so i changed the pressure switch and now i have hardly any flow at all.
No flow at all at the brush head,but when i disconnect from the hose reel i do get a flow but it wont make its way through the hose reel! Any suggestions?
-
Could be air disconnect everything then re connect,see if the outlet on the tank is blocked with a coat hanger,you'd be surprised.
-
Try another pump if you have one without fixing it properly first.

Are you using a digi controller? if so does it flash DE and the pump motor pulse when you attach the hose reel?
1. you could check the flow of the hose reel and wfp by attaching to an outside tap and give them a good blast to see what happens.
2. check to see hose conectors are pushed on properly/not gone faulty especialy if it's a stop end type fitting
3. check to find out if the hose is kinked somewhere on the reel (unwind it all to check) and make sure the internal hose connection is on properly too
4. check to see if the brush justs are blocked
5. check to find if any kinked,blocked damaged pole hose and conector.
Well that's a start to rule out the hose reel and wfp for blockages anyway
-
Plug a connector in separate from the pole you don't need to plug your pole in I have a little piece of pole hose and a snap fitting on the end.

Re calibrate the pump. The cold weather makes hoses stiffer and swell up. If you use a flow controller it's easy to do.
Had to recalibrate mine from 35 up to 50 just a few weeks into winter as flow became intermittent.

Thanks to all,i have used another pump which i had spare and all is well! However i would like to keep the existing pump as a spare and so need to know what,if anything,can be done to get this pump up and running as it was.
I dont use any controllers or cut off switches so it is a simple setup(Pump and battery)
The thing i need to know is,do pumps "fail" over time and become less efficient.I had been told,in the past,that they either work or they dont,but now i am not so sure.As i have previously stated i did change the pressure switch but no improvement.

What make of pump is it n how old is it
-
It could be the carbon bushes that need replacing . You can get a replacement kit .

If changing the pump resolved the issue, It would appear that the older pump may have reached the end of its useful life. Dependant on its age Pumps do wear out, anything from the pump motor not running as efficiently as it used to or even the valve in the pump head wearing out.
It could as already suggested be that the pump motor brushes are worn or full of dust, Also it may be that that something has blocked the pump head valves. The only way to see if this is the case would be to remove the pump head.
