winterizing a pressure washer

How do you do it

Landa hot, burner coils etc
compressed air?
RV antifreeze?
or?

I use R antifreeze, seems to work.

Don't know about one with a 'burner or coils' but we sell a Briggs and Stratton product for the Troybilts and other el-cheapos called "Pump Saver' You just hook to the inlet, remove the pressure hose or hold the wand valve open and spray it through. It contains some kind of soapy-feeling lubricant for the O-rings and some type of anti-freeze.

Well that went well, RV antifreeze,

We don't have a "hot water" pressure washer, but do have a small electric as well as a gas powered model. Both units spend all winter in an unheated outbuilding with temps getting down to -40F. All I do is run the pump dry, and then tip the unit and shake any remaining water out, making sure that any valves are open. I also thoroughly drain my hoses, simply because the water always seems to find the perfect time to leak out.....when I least want it to!

I would imagine your unit has a drain that will adequately allow the majority of the water to escape.

All that said, water only expands about 10% as it freezes, so basically just releasing any pressure "should" be enough in a pressure washer.

I just put mine at the foot of my bed. Still works after 6
years.

If yours has the tank style water inlet it is easy. Just remove the nozzle and then put RV antifreeze in the tank. Then run the washer pump while keeping the tank full until you get the RV antifreeze out the hose.

Before I had a heated shop I used mine all winter. I would hook the water hose up and then run the pump until the antifreeze was just about out. Then turn the water on. I would catch the antifreeze until I started to get straight water. Then just reuse the caught antifreeze. Every now and then I would add new antifreeze.

Do not trust blowing it out with compressed air. If you do not run the air long enough to dry the water circuit out you will still have water pool after it sets. This will freeze. Usually in the pump or control switches first.

If yours does not have the tank style water inlet you can still get antifreeze in it. Run the water until it is primed with regular water. Then take a bucket full of antifreeze and a short hose with a garden hose end. You want the bottom of the bucket to be above your washer. Hook the short hose up and stick it in the bucket. Your washer should suck enough to get a siphon started. Then just run it until you have antifreeze coming out.

If it expand 10% then the crack in the pipe or fitting will 10% of the inside circumference, still going to leak a lot!

X 2. This stuff works great. I just spray enough till it starts to foam out the pump outlet. Never had a freeze up, and I use a pressure washer in the winter A BUNCH. It's a John Deere, didn't really think it was that "el-cheapo". :lol: HTH.

The cheapo pressure only units like the Troy built like my friend has, needs that lubricant every year even if they are kept warm. Without it the aluminum inside will corrode. Many are rated for a fifty hour lifetime.

I used rv antifreeze until my power washer dealer said use winter time window washer fluid it might turn slushy in extreme cold butwot
freeze and does not need to be cleaned out to use washer just start it up.

I took a funnel and clamped a short piece of garden hose with
male threads. When I?m done or it starts getting cool screw it
in throw some RV antifreeze in the funnel and pull the rope a
few times. Works great for me

I simply move my small one into the basement.

I made an adapter and air blow mine.

pump saver is best and easiest and cheap

On my landa I just dump a couple gallon of antifreeze into the water reserve tank
and run it till the antifreeze comes out the nozzle.You can mix it 50 50 before
you poor it in.

I've seen RV antifreeze freeze up in the jug setting outside.I use the green stuff.

Don't forget the tank and the carburetor.
Drain them and then blow them dry with compressed air.
