The Tucker 20066-R is a genuine 30-inch RHG reverse osmosis membrane insert for the Tucker T-4060 RO/DI window cleaning cart. The RO membrane is the heart of a pure-water system: it removes the bulk of dissolved solids from incoming tap water so the downstream DI resin only has to polish the last traces, which is what keeps resin cost and TDS creep under control.
Built for
This insert is for window cleaning contractors and facility teams running a Tucker T-4060 cart who are seeing rising TDS or falling pure-water output. Keeping a spare membrane on hand means a crew is never sidelined waiting on a part when production water quality starts to slip.
When to replace the RO membrane
Plan on replacing an RO membrane roughly every 2 to 3 years, but let your water tell you: a membrane that has begun removing less than about 80% of incoming impurities is due. If TDS output is climbing, first try flushing the membrane for 1 to 2 hours; if elevated TDS persists after a good flush, the membrane (or the DI resin behind it) needs replacing. Because output and membrane life both depend on incoming water hardness, hard-water regions will replace more often.

Frequently asked questions
Which Tucker cart does the 20066-R membrane fit?
It is the 30-inch RHG RO membrane insert for the Tucker T-4060 RO/DI cart.
How often should the RO membrane be replaced?
As a rule of thumb, every 2 to 3 years, but replace sooner if it removes less than about 80% of incoming impurities or if TDS stays high after a thorough flush. Hard incoming water shortens membrane life.
My TDS is climbing - is it the membrane or the resin?
Flush the RO membrane for 1 to 2 hours first. If TDS drops, the membrane is fine and the DI resin likely needs replacing. If TDS stays high after flushing, the membrane itself is due for replacement.
Why does the RO membrane matter so much?
It removes most dissolved solids before water reaches the DI resin, so the resin lasts far longer. A healthy membrane is what keeps pure-water output high and cost per gallon low.
