Winterizing

When I winterized my previous toy hauler, I was lucky that I only had to use 2 or 3 gallons of RV antifreeze poured into my fresh water tank to winterize. The water pump input was located at the very bottom of the freshwater tank and was capable of pulling nearly all the water from the freshwater tank before I poured the 2 or 3 gallons of RV antifreeze into the freshwater tank--very little dilution of the RV antifreeze.

On my current toy hauler my water pump starts pulling air when there's still 2 or 3 gallons of water in the tank. I can drain this out via the freshwater tank drain valve so it's not an issue in terms of emptying the fresh water tank for the winter. However, it does pose a problem with getting concentrated RV antifreeze into my toy hauler.

Was wondering if there's a drawback to installing two-valves on the freshwater hose leading from the freshwater tank. Was considering installing one "T" connector (with a valve and hose attached) that would allow RV antifreeze to be accessed by the water pump directly from the RV antifreeze container, while the 2nd valve (located closer to the freshwater tank) would isolate this process from the freshwater tank itself.

Will this work? Is there a better way to do this?

Thanks!

    Yup, have a water heater by-pass. Easy access. No problem there.

    Are you saying the two-valve idea I mentioned is commonly used on RV's? for winterizing purposes?
