go with the 14mm it's a higher pressure hose.

Hi Trevor
You have one of two problems
1. Pressure relief valve is stuck and needs cleaning or replacement
2. Pistons that pressurize the water need new sealing rings or seals

Every 5.5 HP pressure washer runs between 2,200 and 2,500 PSI with most set by the manufacturer at 2,400 PSI with 3,600 RPM of engine speed.

Due to the power required to produce more than 2,500 PSI a 5.5 HP engine would lose engine speed as it can not produce enough power for the higher PSI output. It is a matter of hydraulics vs input power.

Any gas pressure washer will produce lower pressure with lower engine RPM. Looking at S2350 as your model number yours may be set to 2,350 PSI by Simoniz.

Thanks for using FixYa.

I contacted the Company in US.

Thank you for keeping in touch.

Can anyone Solve this? My simoniz S2500 gas powered pressure washer has low pressure coming right from the outlet. It used to be high pressure until now.. I think it has something to do with the pump and if so, is there anything I can do to repair this problem? The screen is good; water comes out of the hose good, wand is ok......Just that lower pressure is at the wand even at high settings....It comes in a form of a spray in both modes......

I have a SIMONIZ S2000 electric. I bought the unit about 8 weeks ago used it once. On the second use yesterday the unit didn't work as well, the pressure seemed only a bit better than hose pressure and soap did not dispense at any pressure. SO.... after much thought I turned the hose/tap pressure down so that I only got about 2-3 GPM instead of the typical 5-6GPM normally coming out of my hose....... it worked! Soap dispenses and spay is way better! It seems that if if the inlet hose pressure is high the pump doesn't work as well... go figure.

Hi my simoniz electrc power washer will not go off when I release the trigger , leaks trough the water inlet hose , I replaced the O rings but keeps leaking ..THANKS
