Eliminate Grey Water Tank

We had a 2007 E350 Sportsmobile outfitted for handicap accessibility. We chose to eliminate the grey water tank and only had a black/waste water tank. We kept a small sink with 6 gal freshwater tanks that also drained into the black water tank, outside shower attachment and NO water heater. This worked well for us. Only had to drain a single tank to drain.

We did exactly what u r considering. Sportsmobile did the pop top and we did the rest. 20 gallon fresh water, 5 gallon interior grey water under sink/faucet. We drain grey water ourselves by opening cabinet and quick disconnect on sink drain. We chose not to do a bigger grey water tank due to space. Obviously, need to make sure we don’t overfill custom grey water since it is 1/4 size of fresh water tank. It’s great for washing hands, brushing teeth, even washing hair in sink. We also did an exterior shower out back door. We have a 2.5 gallon water heater (110 volt)-only takes 10 min w van running or shore power to heat up water for quick shower, dishes, etc.

Very interesting thread - lots of good info.

i just rented a WanderVan recently... it had a very small cabinet with a manual hand pump for water, with a small fresh and a small grey tank all in the base of the cabinet. Very space efficient, and a clever low tech solution.

We pulled our H2O heater. Too much wasted water in the line between the faucet and the heater tank. Just as easy to heat water on the stove for dishes, etc., with solar shower for heating outside. Plus, you effectively end up carrying an extra 50 lbs. of water that you can’t pump out of the heater. We put a locking door on the old vent space and now have a lovely storage spot that is accessible from the outside.

Our grey tank is a backup for sink spills. I don’t remember the last time we drained it. We have a plastic tub in the sink. Dump it outside after use. Works even in no-no places.
