Can you make your own pump saver? - Machine Repairs - Pressure Washing Resource

post by Hologram on Nov 1, 2014

Ordered my first pressure washer and already bought some pump saver in the screw on bottle. I plan on using it after every use but seems that would get costly. I read somewhere you can mix 50 50 RV antifreeze and mineral oil. Not sure what mineral oil you would use though and if it’s even a cheeper way.

I’ve used straight rv antifreeze or the old school green automotive antifreeze for years.

how about windshield washing fluid…its rated to -20 deg and is only 2.00/gallon

Do you just gravity feed it until it runs out of the outlet, or do you pull the cord a time or 2 to circulate it in the pump?

I have a tank that gravity feeds to my machines. I start them up and let it flow through everything. You can also use a 12v pump of just about any type to push it through your system.

Ive seen a few guys post that they were using it. I’ve never tried it.

Best to use is a 50/50 antifreeze mix. Buy It straight and just mix equal parts water to it. Best bang for the buck for antifreeze that way. You can also use Windshield wiper fluid. What we do is have a spare tank and quick connect the bypass line to it and ball valve the mix into the pump. This way we can keep reusing the 50/50 antifreeze mix through out the year.

Also blow out your hose lines, surface machines and guns/wands with an air compressor that way you have Zero concerns.

In 20yrs in business we haven’t lost a pump yet to freeze
