Do-It-Yourself Basement Pron

Documenting my little "never want to empty that dehumudifier bucket again" project.


(A) Bought a small drain hose ($7, Loew's) which screws onto the dehumidifier drain, directing extracted water into

(B) The reservoir of the sump pump (Little Giant model VCMA-20ULT, $45 online including shipping and handling). When reservoir is sufficiently full, the pump turns on, sending water through a check-valve into

(C) 3/8" plastic tube, which I've run up the wall, into the ceiling, and down to the

(D) washing machine drain, where it empties. The pump turns off when its reservoir is empty, and the check valve keeps the water from flowing back into the pump reservoir.

The only improvements I might make are:

(1) Place a shallow plastic tray or container under the dehumidifier and sump pump in case of some sort of failure or loose fitting. Just an extra level of safety....

(2) Run the drain into a large container with a tap or faucet (like a water cooler) which I could then recycle for houseplants / grey water. Although I'd have to be sure that did not overflow.....

The pump is very quiet, I almost never catch it working, especially compared to the relatively loud dehumidifier. FWIW, I also have purchased a high current receptacle timer, designed especially for motor drive appliances, to cycle the dehumidifier (on at night, off during the day) if the cycling starts to bug me.

The Model VCMA-20ULT is perhaps a bit overkill (20' Head, 1.3 Gals/min) for my application, but there was not much difference in price between this and the next size down, so I thought it best to be conservative.
