"Excellent service - Charlie was responsive regarding the quote and the service. I was notified of any potential delays and Charlie provided me with multiple options every step of the way. Service was provided in a careful manner to ensure all of my property was protected (floors, walls, etc.) and following installation of the new water heater all of the mess was cleaned up. I am very happy with the overall service and after obtaining multiple quotes I believe that the service I received from Charlie was not only reasonably priced, but was very high quality. I would take into consideration Charlie's competence along with the price when evaluating any cost estimate from him. I think he's your man if you need something difficult done - he's more than willing to make the square peg fit into the round hole."

"Every things that these Plumbers did from greetings/conversation with me to the installion & clean up of my bathroom sink was just awesome. I would highly recommend them. The only negative remark toward Big Wrench Plumbing & Sewer is the Cost/Charge to do this was too high. Don't get me wrong everything else that was say/done to installed was just awesome."

Sump Pump Installation questions, answered by experts

A water pressure booster doesn't require special maintenance. Like any house system, inspections should be a regular part of your annual schedule. Check for leaks, faulty valves, pressure loss, and mineral build-up. Pressure loss could be a result of mineral build-up, and you can descale the system with a vinegar and water solution.

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

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.
