I previously posted that I have a KEW Hobby pressure washer ...... been
great to date ..that had started surging.
No shortage of incoming mains (pressure or flow rate) even tried different
hoses & fittings to be 100% sure of that.
OK - as hose was crumbling away, .... bought a new hose, incl hose fitting
.... so can now discount the hose, lance & nozzle from being the issue.
Loads of water through lance if trigger operated (motor off)
When motor is on ... when lance operated it is surging ... aprox 2 sec full
pressure 1 sec low pressure.
Now previously it was mentioned that when I release trigger .. pump still
runs, and it uses a bypass valve to release the pressure .. and this could
be at fault.
Anybody know what this would look like, and is this something worth
stripping & perhaps cleaning.
Last option I suppose would be if there is somewhere that services KEW.
Like many British Manufacturing companies - they are no more.
