Washer - Drain Height
The flow rate of the pump is dependent upon the height of the drain pipe. For each 1 foot of additional drain pipe height, the flow rate will be reduced by approximately 1 gallon per minute.
The washer pump will pump water at a rate of 15 gallons per minute. Compact washers can pump up only 5 feet.
The drain pipe should be a minimum of 1½" I.D. (inside diameter) to assure proper draining. The washer drain hose is 1¼" O.D. (outside diameter). To be confident that no siphoning of water will take place, the drain plumbing should be a minimum of 30" high.
In order for the drain hose to function properly, the drain must be at least 30" from the floor and less than 8 feet high.
Note: If drain is not 30" high, we have packed with new washers, in the installation package, an anti-siphon clip that attaches to the hose and the back of the washer to lift the drain hose up higher.
