How do you size a sump pit?

How to calculate the sump pump capacity you need

1. A sump pit receives 20″ of water in 1 minute, or approximately 20 gallons.
2. Multiply: 20 gallons x 60 minutes x 1.5 = 1800 Gallons per Hour (GPH) capacity needed.

What diameter should a sump hole be?

18 inches

What drains into sump pit?

Water flows into the sump pit through drains or by natural water migration through the soil. The sump pump’s job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry. Today, sump pumps are common in new construction homes.

What size is sump pump discharge pipe?

1.5 inches

How deep should I bury my sump pump line?

Dig a trench for the sump pump drain line that is at least 2 feet wide and the depth of the frost line in your area, plus an additional 2 feet. For example, if the frost line in your area is 12 inches, dig the trench 3 feet deep.

Can you run sump pump into sewer?

Aside from the fact that connecting sump pumps to the sanitary sewer is illegal, it can cause significant health and safety risks. Sump pumps are designed to pump groundwater and rain water. Generally, the sanitary sewer pipe in the street is only 8 inches in diameter, and often the pipe slope is not very steep.

How do you keep a sump pump line from freezing?

The best way to prevent a discharge line from freezing is with as much insulation as possible. To achieve this, you can try burying the line deeper underground, or try adding insulation using hay and a tarp. Give your sump pump a slight slope.

Why does my sump pump keep tripping the GFCI?

Sump pumps commonly are required to have GFCI protection, either at the wall outlet they plug into or on the circuit breaker itself. In any case, a GFCI still needs to do its job, and if a pump is poorly designed or is malfunctioning, it could produce a leakage current that trips the GFCI.

Do all outlets in a basement have to be GFCI?

GFCI protection is required for 125-volt to 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to the ground. GFCI receptacles are required in bathrooms, garages, crawl spaces, basements, laundry rooms and areas where a water source is present.

What is code for outlets in basement?

The national electric code calls for outlets on walls every 12 feet, on any wall wider than 24 inches, and GFCI (ground fault current interrupter) outlets in bathrooms and above countertops. You’ll need to add a 15- or 20-amp circuit breaker or two to your electrical service panel.
