Signs You May Need Sump Pump Replacement

Age

The average lifespan of a sump pump is around ten years. Once your sump pump begins approaching ten years of age and experiencing frequent repairs, you will likely need to have Steve’s Plumbing and A/C replace your sump pump with a newer one.

Sump Pump Will Not Run

Any time your sump pump will not turn on and run, unfortunately, you have a major issue on your hands. There are actually a number of reasons that your sump pump may be experiencing power issues including the float switch being stuck or broken, a jammed impeller, a potential loose electrical connection, a burnt motor, or your sump pump has just plain hit the end of its lifespan. Whatever the case, if your pump is older and not running, you may need to think about professional sump pump installation and replacement services from Steve’s Plumbing and A/C.

Contrarily, if your sump pump is always running, and never seems to turn off, this is also an issue. This is normally due to a float switch issue, which will need professional assistance from Steve’s Plumbing and A/C. If your sump pump is not turning on at all or running constantly, repairs can be possible, but you may need to start thinking about replacing the machine completely.

Odd Noises and Vibrations

Any time your sump pump is making loud noises such as grinding, banging, rattling, or vibrating, you are almost guaranteed to have a serious issue. These noises are indicative of a problem with your sump pump and will require a diagnosis from Steve’s Plumbing and A/C in which you may want to consider fully replacing the sump pump all together.

Irregular Cycling

Irregular cycling of your sump pump can occur for a multitude of reasons such as a broken float switch or the float valve being too low. No matter the case, irregular cycling, particularly in conjunction with any of the other listed symptoms, is never a good sign and will need to be addressed by plumbing professionals at Steve’s Plumbing and A/C as soon as possible.

Clogged Pump

Debris can naturally flow and build up in your sump pump, leading to a pretty severe clog over time. Clogs can damage the impeller fan in your sump pump which will detrimentally affect your system. Additionally, the pump line hose can also become clogged with sediment and debris, causing major issues for your sump pump. No matter the issue, you will need to consult with Steve’s Plumbing and A/C about repair and possibly replacement options.

Empty Water Pit

Unfortunately, many homeowners get taken advantage of by inadequate plumbers around the area, leading to incorrect installation of their home’s sump pump system. If there is no water in the pit but your sump pump is still running, your sump pump was likely installed incorrectly and will need to be corrected and potentially even replaced by the plumbing experts that you can trust at Steve’s Plumbing and A/C.

We ensure your new sump pump is fully operational and ready to help you weather any storm.

Sump Pump Installation In Oahu, HI FAQs​

Sump pumps are less common in Oahu than on the mainland, but they’re genuinely useful in specific situations. Homes with below-grade spaces, low-lying yards that collect water during heavy rains, or properties near streams and drainage channels can benefit from a sump pump to remove groundwater before it enters the structure. Hawaii’s intense rainfall events can send significant water volume toward a home’s foundation quickly.
Pump sizing depends on the square footage of the area being protected, the typical rate of water intrusion, and the height the pump needs to lift water to discharge it. Most residential applications use pumps rated between 1/3 and 1/2 horsepower. A technician will assess your site conditions and calculate the right capacity for your specific situation rather than guessing at a standard size.
A sump pump sits in a pit, called a sump basin, that’s dug into the lowest point of the area being protected. Groundwater and surface water drain into the basin, and the pump activates automatically when the water level reaches a set float height. A discharge line runs the water away from the foundation to a drain or outdoor discharge point. The installation location is chosen to intercept water before it can spread into the living space.
Installing a sump pump in a space that already has a sump basin typically takes a few hours. If a new basin needs to be excavated and the discharge line routed, the job can take a full day. Steve’s Plumbing & A/C Service will assess the site and give you a clear timeline and cost estimate before any work begins.
A battery backup is worth considering, especially for properties that need the pump most during storms, which are also the times when power outages are most likely. A backup system keeps the pump running even if the main power goes out. Combination units that run on AC power normally and switch to battery automatically during an outage provide the most reliable protection.
