Distilled water rinse after ultrasonic cleaning

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.

l give it a few turns in my SpinClean after the US

I do too. My US is a cheap $100 one. I guess it does it’s job. I see residues even after cleaning about 50 brand new records. (I had bought about 100 sealed classical albums mostly from late 70s and 80s). I feel new records made recently are worse. They are dirtier and also sound terrible especially those selling at around $20.

Added a couple pictures on my systems page.

@slaw,

After looking at your photos they appear to show the filters mounted on the suction side of the pump Bayite . If this is correct - If I might offer a suggestion - install the filter(s) at the pump discharge side. The filters will present a pressure drop and the pump suction side only has about 7-ft of suction head. Check the filter cartridge max differential pressure rating - most will be >15 psid (>35-ft head equivalent) so to get maximum use, fine filters are generally installed at the pump discharge - and your pump has an maximum discharge head of 80 psi.

Since you are pumping relative clean water (no stones & pebbles) you do not need a suction strainer. If you do replumb, since you do not have a differential pressure gauge on the filter or pump - keep an eye on the filter and pump noise and the power supply temp, As the filter loads and water flow pressure drop increases - the pump discharge head (being a positive displacement pump) will increase to maintain flow until it reaches its maximum. But its maximum (80 psid) can collapse most disposable filters. But as the pump discharge increases so will its noise and the 120VAC/12VDC power supply will heat up because the pump is drawing more current.

Just some thoughts for you.
