pressure washer outlet image
Lubyloo
I want to get a pressure washer to use in cleaning the front porch, driveway, and siding of my home, but my house has low water pressure. Would a pressure washer still work in this situation? I guess I don't know how a pressure washer works - I assume it's hooked up to a hose on the house??? Thanks.
Answer
It really depends on what you call low. If its too low the pressure washer will 'hunt' or surge up and down on the outlet pressure and will eventually damage the washer unit. Your guess is correct it is hooked up with a hose to the house and a very long hose of too small a size will have the same effect as low water pressure. Check with manufacturers instructions or seek advise from the supplier but I would hazard a guess you need about 18/22 psi minimum.

Why I have no pressure on my pressure washer?

My pressure washer starts quickly, runs good, but my pressure stopped. Hoses not clogged, have water coming thru wand, but no pressure. How do I fix this?
Answer
If you've ever run the pump without water pressure being on it then you can suck the seals loose. Sometimes they will reseat, other times not.
When you last used it - if it was last year, before winter, and you didn't winterize it the seals may have dried out. Just about all hardware stores carry a seal conditioner for pressure pumps. It lubricates and conditions the seals while also removing water from the pump so if the weather freezes you don't crack the pump housing. I've bought many pressure washers that have experienced this problem. People in my area fail to winterize their pumps and end up with junk. They still have a good engine on them, but the pump must be replaced.
With your pump, check for leaks. If it's not leaking anywhere then that's a good sign. There is a pressure regulator on the outlet side that when there is sufficient pressure the high pressure water is diverted back to the inlet side. That's so the pump doesn't stall the engine or blow the hose.
CAUTION: IF YOU MESS WITH THAT SETTING YOU CAN DAMAGE THE PUMP OR EVEN DAMAGE YOURSELF. YES, YOU CAN GET HURT IF IT'S NOT DONE RIGHT. If you DO remove it, make sure you carefully count the number of turns to put it back exactly as it was before you took it off. There MIGHT be soap residue keeping the pump from building high pressure. The water can be going in circles.
There's a lot to pressure washers you wouldn't think of. These are just a few possibilities.
Best of luck with your project. AND BE CAREFUL.
