Sump PumpA sump pump is an important part of a home inspection. It is the first line of defense against moisture in a basement or crawlspace. So what are some important things to inspect on a sump pump?

Check Valve – With the same diameter as the discharge pipe, this should be placed within the system to prevent water from coming back into the home and trench as soon as the system deactivates. When this valve is missing, water will re-enter the pit and the sump pump will keep activating unnecessarily because it will keep shifting the same water up and down the pipe. Additionally, there is the rare possibility that the discharge line is connected to a pond or stream and this water could back up into the sump pit which causes all sorts of new issues.

Size – In terms of the sump pit itself, it should be large enough for the pump. Despite popular belief, there aren’t any requirements for material but it does need to be solid and it needs to hold a pump for a considerable amount of time. With a pit that is too small, the pump won’t work as efficiently as it could so the minimum depth should be 24 inches with 18 inches in width. Most commonly, sump pumps fail because the float gets jammed and this results from the whole system being too cramped.

Cover – Finally, we should also mention that a cover prevents water from evaporating and entering the home. Without a cover, moisture can occur which then leads to mold and other problems.
