What this site is
Pit and Pump is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and a discharge connection is usually a permitted alteration — ask to see the permit. We carry out no work, we sell no equipment, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.Checking a credential in Delaware
Delaware licenses are issued by the Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners, which publishes a public search you can use before work begins.

What that coverage looks like
Of the 96 ZIP codes we cover in Delaware, 51 are in New Castle County and 25 in Wilmington. Storms do not respect that distribution: a single night's rain across 3 counties produces far more pump calls than any contractor can answer at once, which is the argument for testing yours in the dry.
How a sump pump repair job goes
A sump pump is tested by filling the pit, not by listening to it. The float has to lift, the pump has to start, the check valve has to hold and the discharge has to run clear of the house. Any of those four can fail silently and none of them announces itself until the night the pump is needed.
What the call asks about sump pump repair
- Whether the pump runs at all when the float is lifted by hand.
- Where the discharge goes, and whether it is frozen, blocked or running back into the pit.
- Whether there is a battery backup, and when it was last tested.
