Compressor question

Trying to use a pressure washer as a hydraulic source will almost certainly result in a receiver failure ! Many pressure washers run to 1500psi and some MUCH higher ! 1.5 X working pressure eg 150 = 225 psi Noel.

+1 for Noel's warning!

Only if the tester is so dumb that they do not Tee-in a bypass, so the pressure at the receiver is carefully adjusted. I did write the word ‘carefully’ in my reply, but I do know that many don’t take notice of what is actually written.🙂

I expect a diesel fuel injector ‘pop-tester’ could be used to raise the pressure - but with such a small volume per stroke and hand operated it would take a while.🙂

Doubtless some pressure washers will attenuate to a quite low pressure delivery - but, yes, any dim-wit supplying full pressure directly from a pressure washer (100Bar upwards) could end up with a scrap receiver.

Unfortunately the term ‘engineer’ (in the forum title) does not run true to the term when used to describe a proper engineer.

If it worries you this on ebay won't break the bank, they seem to be stupid money these days

Looks ok if it is accurate ? .....does it have a compliance certificate? lol

Regardind engineer, we don't want to be known as the nanny state forum, do we.

Rules are made for the obedience of fools and the guidance of wise men?

Another old chesnut the just surfaced

There are old pilots and bold pitots, but there are no old bold pilots?

Think on.......

Here is a typical non-engineer youtuber showing how to test a receiver using a pressure washer. Fairly good but I would use a Tee, with a valve, to be sure that most of the pressure washer volume could bypass the receiver.

A simple risk assessment is all that is needed. He didn’t consider how to limit the pressure if a pressure washer fault occurred. Very unlikely, but for the cost of a Tee-piece and a valve, is it worth taking that risk?
