Does anyone know where i can find a new regulator? This one sprung a leek.
The leek is hard to see but its right behind the blue hose. Im pointing to it in the one pic.

That's a pretty common unloader. You should look at the color spring inside the black knob when you disassemble it and likely reuse it upon reassembly. Most are rated to 200° and 3000 psi minimum. The $60 ones on Amazon have worked flawlessly for me. You might want to consider a couple well placed pressure washer QC's to make reassembly a breeze.

Thanks Jim, do i just call it a pressure Washer unloader ? If you have a link to the one on Amazon would you mind sending it.

Good video example of the difference in pressure regulation and an example of a typical unloader. You can get various springs and pressure ratings along with larger npt inlet sizes. Try to match yours as close as possible for ease of install.
Thanks Jim, i knew you would have the answer i needed.
Have a great day.

No problem, you can pop the top off the knob and unscrew the knob retaining nut and check the spring color quickly before you order the replacement.
Hey Jim , i got the new one on exactly the same as the old one but i don't see any pressure. Does it take a minute because the lines were removed?

Does it matter what side port is used? I didn't think so since the flow only goes in one direction into the front port and out the side port.

With everything reassembled following the flow arrows and purged of air, you should only have to readjust the pressure. The side ports are universal and you can use whichever one you like.

Hi Jim, hope you and your family had a great Thanksgiving.

I now know why my pressure regulator sprung a leek also my new spray gun wouldn't stop spraying after i let go of the trigger and why a little rubber o-ring clogged the green spray tip.

Apparently there is a difference in the spray tips other then the color. I didn't realize this and must of had a smaller size then i actually needed causing too much back pressure.

I just picked up the correct tips for my GPM & PSI that ill be using. As they say you learn something new every day.

We had a great Thanksgiving and I hope you did as well. Glad you got it sorted out and figured out what was the culprit, always something to learn.
Hi Jim, im having trouble maintaining a consistent PSI with that new pressure regulator. It seems to float all over the place. Do you have any thoughts on what might be the problem? Remember i use a 2 GPM green tip and messed up the old regulator with back pressure.

What exactly is it doing, how many hours?
I'll set it to 1200 psi it will stay there for a couple seconds then sink down to nothing. Then ill turn the knob just a little bit and it will shoot up to over 2000 psi but won't stay there either. I just cant seem to set it on a psi number i want and have it stay there.

Its hard to tell. I'll have to test it. In the house using the spinner it would take a few minutes on the trigger for the psi to come up. Then my helper said it was holding at 1300.

Lack of flow and initial pressure has me leaning towards the intake side of the pump starving. How many hours since the seals and valves on the pump were rebuilt? Intake hose, all incoming water screens free and clear?

I don't know. I never did that. I have very little hours on it. It was working just fine before the back pressure problem.

Try testingflow with just a blank QC on the solution line. Start at an idle wide open flow, throttle all the way up, does it deliver water like it should increasing flow with RPM's?
