A couple of processes: dawn detergent and ice on a summer day works "slick".

Spray lube valve rods where possible.

Or as I do:
Valterra Back Flush Valve $42 on Amazon. Gets everything OUT and you have a view cap to see when it runs clear. EZ directions.

Thetford DRAIN VALVE LUBE: $11.39 on Amazon. Designed to lube the internal rod components.

Lastly NEVER leave black tank drain lines OPEN when on site. Seals dry out and sewer smell is not good with dinner!!

Frequency depends on your RV use. It took longer at winterization to ensure all systems were clear before adding anti freeze. I use very little water and anti freeze in the holding tanks.

Easier to prevent than to clear up. Works for me.

I empty and flush my tanks every weekend and take tank monitors do not work but no a big deal I have never had s--- on my floor yet.

Never had a tank sensor work properly never worried about it ...... Just after the years have a good idea how long the tank takes to fill........ the trailers of our past did not have them............

I built my own lance for black and an separately for grey, both have ball valves for local control. Lances were tested on the lawn to provide low volume high velocity jet stream. They will thrust like a jet engine and strike nearby surfaces very hard, just what's needed. Forgotten the orifice size where ideal, maybe 3/32-Click image for larger version

The grey tank washer is similar but uses hose to snake down tank vac vent below bath tank in Georgetown.
Both jets must be lowered 1-2 inches at a time and rotate full circle. The key is concentrate in direction of sensors for good scrub.
Of course the level systems are indicators, not gauges i.e.:approx levels, still nice to know "almost empty or full".
