Distilled water rinse after ultrasonic cleaning

Hi @noromance. I use brass fittings that are barbed on one end then flexible hose rated for high heat.

Thanks but how do you use the filter? Isn't there just a drain on the unit, so how do you pump it out > filter > back into tank?

@noromance,

I connect the tank drain to some hose that travels to filter "1 then another length of hose to filter #2, then another length of hose to the RV pump, then a long length of hose that I manually hold inside the tank when the pump is running.

The second filter isn’t necessary. I was experimenting and tried it this way. What’s more important is filter surface area. The 10" filter provides this. I like the clear filter housing because you can see what’s going on.I change water about every 6 weeks. I pull the tank drain hose off, take the tank to the sink and empty it. Tank back in place now.
Put the hose into a new gallon of distilled water, hold the hose into the tank at the other end, turn on the pump and this washes the line/filter out. This pumping process takes 30 seconds. Empty the tank into the sink again. Reinstall everything and add fresh water. I use Versa-Clean at 2oz. per gallon.

FWIW, the thread, Thumbs up for Ultrasonic Cleaning , has good info.
