How to Hook a Sump Pump to a Garden Hose

Sump pumps are used in basements, crawl spaces and other areas where unwanted water tends to gather. These pumps are activated when the water in the sump basin reaches a pre-set depth. The water is then pumped out of the basin and away from the home. The method and materials used to construct the drain line can vary greatly from one application to another.

Step 1

Locate the sump pump and determine the type of drain currently in place. If installing a new sump pump, proceed to step 2. Use the hack saw to cut through the drain pipe just above the top of the basin. With the drain cut, lift the sump pump up and out of the basin. Remove the drain pipe from the outlet port of the sump pump using the pipe wrench if necessary. With the drain line removed take the opportunity to inspect the interior of the pump for any loose debris or obvious damage. Discard the old drain and clean the outlet port of the pump.

Step 2

Install the threaded adaptor into the outlet port of the sump pump. Be certain it is secure but take care not to over-tighten. The adaptor and outlet port will both be made of plastic and can crack or break. A snug secure fit is adequate. Once the adaptor is in place, connect the garden hose to the pump. This fitting also needs to be snug, but do not over-tighten. Carefully lower the pump back into the basin, making certain it sits level on the floor of the basin.

Step 3

Route the water hose up and away from the sump basin. The hose may have a tendency to coil in the bottom of the basin if there is any slack in the hose. This can interfere with the operation of the pump and must be avoided. Take the hose up to ground level and either drill a new exit hole, or use the hole used for the previous drain. The hose can now be connected to a soaker hose or other application to make use of the water being removed or simply placed in a location to dispose of the water.
