Hawk pto washer woes

westlander

Evening,

I have an old hawk pto power washer couldn’t tell you which model. I have a new turbo head and lance fitted and was working fine until today it suddenly lost pressure.

Anyone know how to check if the unloader valve is faulty?

i see it moves up when I press the trigger and then it goes down when you release the trigger but I hear what sounds like air coming out of the unloader valve when I keep the trigger pressed on the lance. Some water is coming out of the turbo head but not enough to work the turbo head.

Anyone had similar problems ?

the suction hose line going into the icb tank is fine as I see a good flow of water returning when trigger is not pressed

Any good sites for buying replacement parts ? A quick Google gives fox’s.ie

thanks for reading

I’ve a hawk washer too and it’s very temperamental with dirt on the filter or in the gauze in the pump,

I used get problems with the gauze blocking in the pump after I bought the washer 2nd hand about 15 years ago. I haven’t had to go near it in the last 10 or 12 years. I wonder has the op a build up of lime or gunk in the internals of the pump?

Have you checked the filter on the inlet pipe?

Yes the filter that sucks up the water and the little gauge filter in near the pump side are 100%.

Tbh I might have to bring it to some experienced fella you would be a bit reluctant to throw parts at it they don’t be long adding up.

on a side note I see hawk pumps on sale for about 800 euro new in homeland.ie you would be tempted !!

The Nutty M

Could be something as small as a piece of crap in the valves. A valve not seated correctly will give you a loss of pressure. Easy enough to screw out and check for a small bit of crud.

Better start with the basics.

I got mine serviced at EPS in Ballyhaunis a few years back, sound to deal with, it was something simple that was gone in mine, they replaced for a few euro, running perfect since.

Well thanks for all the replies and things to check. I got sorted. The connector that the hose fits onto on the pump side: I decided to whip it off and low and behold there was a piece of what looked to be small rubber that had broken off and hardened and was blocking the water from coming out at a steady pace.

watch out slats I’m coming for you 😁
