Pressure is not operating at the 2200 psi that it should, what could be the problem?

Hi, Garyh623!

What kind/brand of pressure washer is it? Also, this might not be correct, but it's something that I heard, is that the electrical current needs to be large enough so that the pressure washers will operate at their optimum capacity. So, the outlets and any electrical cords need to be strong enough.

Again, that might not be correct, but might be something to consider.

Hopefully, others will also come along to address your question.

Thanks!
