pump clicks into life for about 1 second just enough to make a noise to annoy.
Turn taps on and off works normal but still irritating noise when it shuts off under pressure.
ACTION TO DATE:
adjusted pressure screw, took off pressure switch cleaned checked with OHM meter (elec side working ok), replaced with pressure switch off spare pump - no change.
looked for leaks in every pipe - no leaks found.
Frustrated I replaced the old pump with new pump I had, works 100%.
QUESTION(S):
why does it do this
where could water pressure be bleeding off (if at all) to cause activation
has anyone had similar problem
is the rocker arm inside the pressure switch subject to wear
At $165-180 I'm hoping to resurrect my old pump rather than buy a new spare, however is the problem a pressure problem ie pressure switch or some other at the pump. THE PROBLEM IS ASSUMED TO BE THE OLD PUMP AS THE NEW ONE WOTKS FINE.
Any ideas?
Cheers Baz

Hi Baz421,
These are diaphragm pumps with several chambers and after a while the rubber diaphragms become worn - 10 years is a pretty good innings.
The 1 second surge is the pump trying to maintain the pressure due to the tiny leak in the diaphragm or the valves. Even a new pump will do this every few hours or so, but I'm assuming yours does it more frequently now - like every few minutes.
Sometimes a switch is fitted in the 12Volt supply to these pumps to make sure it doesn't do its 1-second-thing in the middle of the night, and if you're prepared to live with a bit of switch-on switch-off then this might work for your older pump too.
Cheers
AJC

It is almost certainly a tiny water leak, but it may or not be in the pump and could be somewhere after it. If it is the diaphragm, just replace it.
I have one of these that has been faultless for 12 years, so they do last well.
Cheers,
Peter

I just happen to have a Shurflo 2088-473-143, that's about to get binned, on of the fittings broke off the housing. Where abouts in Aus do you live?

Adelaide but about to go to Vic and the NT Ian.
Thanks all I think it's internal in the pump so I'll pull it apart and have a look.

From that reply, I take it you don't want the pump.

Oh sorry Ian I didn't mean to be unappreciative. If I can find the problem and it's internal and fixable yes please.

The housing has one of the fittings broken off, as far as I am aware it was going. It was mounted on a truck for its water supply for cutting tools. Probably had very little use. PM me your address, and I will see what the postage is.
I have a 2088 series water pump,,, 10 years old and I did a temp fix in 2009 on the electrical/pressure shut off. Well something has failed.
See link to ensure we talk about same pump series please.
