Title: Power flight pump proplems
Post by: MAX Carpets on February 20, 2010, 04:14:27 pm: Say that with no teeth in! Anyone have any idea why this should happen. If I put the pressure up maximum to 500psi no problem, as soom as I pull trigger it drops to 100psi and it stays at 100psi?????? Does anyone know why this happens. Thanks in advance.

Cheers!

Justin

It has a smaller 500 psi pump so can`t maintain a steady back pressure when the trigger is opened, thus dropping off. The pump was ok with a 2 jet wonder wand, or 1 jet upholstery tool. You could try smaller jets, but it is good for the pump, as not running such high psi.

Best way is drop the priming hose into a bucket and turn the pressure numpty about 3 turns and let the air bubble out. Once it seems the bubbles have stopped then turn pressure all the way up.then releave pressure backdown and attach the wand etc. I had a similar problem and noticed the handtool wasn't trouble as much as the wand when there was air in the system!!

I was hoping it was something like this. So do I do this with clean water in the tank? How long do you think it would take to clear? Sorry I'm thick as pig poo!

I would recycle the water yes water hate filling porties ;D

Pump head red about £280 black £235 don’t know how much the blue one is?

Striping/fitting depends on how competent you are! Bearing I would renew as a matter of course ;)(don’t use a puller too remove it’s threaded) oh buying a new head may be cost effective ???

These are the poppet valves. As southern counties says
the usual suspects.
