Question 1

What does a sump pump do?

Accepted Answer

A sump pump is installed in a sump pit at the lowest point of a basement or crawlspace. When water accumulates in the pit from groundwater or surface drainage, the pump activates and moves the water away from the foundation through a discharge pipe to prevent flooding.

Question 2

How do I know if my sump pump is working?

Accepted Answer

You can test a sump pump by slowly pouring water into the sump pit until the float rises and triggers the pump. The pump should activate, discharge the water, and shut off when the water level drops. If the pump does not activate, runs continuously, or makes unusual sounds, it needs professional evaluation.

Question 3

How long do sump pumps last?

Accepted Answer

Most residential sump pumps last 7 to 10 years with proper maintenance. Pumps in areas with frequent rainfall or high groundwater tables that cycle more often may have shorter lifespans. If your pump is approaching this age range, having it evaluated before relying on it during a heavy rain event is a wise precaution.

Question 4

Should I have a backup sump pump?

Accepted Answer

Yes, particularly if your area experiences significant rainfall or if a flooding event during a power outage would cause serious damage. Battery backup sump pumps activate when the primary pump fails or when power is lost, providing protection during the exact conditions when flooding is most likely.

Question 5

What causes sump pump failure?

Accepted Answer

Common causes of sump pump failure include a stuck or clogged float switch, a clogged discharge line that prevents the pump from moving water, a burned-out motor from running dry or overheating, power loss during a storm, and general wear from years of operation.

Question 6

Does Downey Plumbing install battery backup sump pumps?

Accepted Answer

Yes. Downey Plumbing, Heating and Air Conditioning installs primary and battery backup sump pump systems for homeowners throughout Downey and the surrounding Los Angeles County communities. A battery backup system ensures your pump continues working during power outages when storm flooding is most likely. Call [phone] to discuss backup pump installation.

Question 7

How often should a sump pump be tested?

Accepted Answer

Sump pumps should be tested at least once per year, ideally before the rainy season begins. Testing involves manually triggering the float to confirm the pump activates correctly, discharges water through the outlet, and shuts off when the float drops. Our technicians perform a full pump evaluation as part of any service visit.

Question 8

What should I do if my sump pump is running constantly?

Accepted Answer

A sump pump that runs continuously without shutting off may have a stuck float switch, a check valve that has failed allowing discharged water to flow back into the pit, or a groundwater table that is genuinely overwhelming the pump's capacity. This condition burns out pumps quickly and should be evaluated by a plumber.

Question 9

Can a clogged discharge line cause my sump pump to fail?

Accepted Answer

Yes. If the discharge line is clogged with debris, frozen, or has a failed check valve that allows backflow, the pump runs against resistance it cannot overcome. This strains the motor and can lead to premature failure. Our technicians check the discharge line and check valve as part of every sump pump service.

Question 10

Does a sump pump require regular maintenance?

Accepted Answer

Yes. Annual maintenance should include testing the pump, cleaning the sump pit of debris, inspecting the float switch for free movement, checking the discharge line and outlet for obstructions, and testing the check valve. A properly maintained sump pump is far less likely to fail when it is needed most.

Question 11

My sump pump is making a grinding sound. What does that mean?

Accepted Answer

A grinding sound from a sump pump typically indicates a problem with the impeller, either debris caught in the impeller or wear on the bearings or motor. This type of noise warrants immediate evaluation before the pump fails entirely. Call {PHONE} to schedule a sump pump diagnostic.

Question 12

Can Downey Plumbing install a sump pump in a home that does not have one?

Accepted Answer

Yes. Downey Plumbing, Heating and Air Conditioning installs sump pump systems in homes that do not currently have one, including excavating the sump pit and running the discharge line to an appropriate outlet.

Question 15

What size sump pump does my home need?

Accepted Answer

Sump pump capacity is measured in gallons per hour. The right size depends on your home's groundwater situation, the size of the sump pit, and the length and rise of the discharge line. Our technicians assess these factors and recommend the appropriate pump capacity for your property.
