"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

Sump Pump Installation questions, answered by experts

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

A sump pump's lifespan is typically 7 to 10 years, though the general range can be anywhere from 5 to 15 years. The specific type of pump is a major factor: pedestal sump pumps last an average of 20 to 25 years, whereas submersible sump pumps last between 5 and 15 years. While pedestal pumps are less expensive to service, they are also louder and more prone to clogging.

Several other factors influence longevity, including the pump's quality, usage frequency, and maintenance schedule. A high-quality pump that is well-maintained in a dry climate may last for two decades, while a lower-quality, poorly maintained pump in an area with a high water table or frequent flooding may fail in six years or less.

Regular maintenance, including annual inspections and tuneups from a professional, can significantly extend the pump's life. It is time to consider a replacement if your sump pump runs constantly, cycles frequently, shows visible rust or corrosion, or trips a circuit breaker. As a preventative measure, many homeowners replace their pumps every eight years. It's also worth noting that a manufacturer's warranty can indicate expected lifespan, and some home insurance policies may not cover water damage from a pump that is past its recommended replacement date.

You shouldn’t shower while a sump pump isn’t working. Although household wastewater isn’t supposed to go into the sump pit, it’s best to wait to shower until your sump pump is running properly and able to move excess water out of the basement. If you need to shower when the sump pump isn’t working, aim for a short shower.
