"My understanding is that the guy that came out to install my new toilet and bidet has actually had more experience with commercial plumbing but you would never know it. He was very personable. Showed up a few minutes late but called and let me know he was running behind and then showed up when he said he would. Very conscientious. Seemed to know what he was doing with the bidet install even though it doesnâ t seem that would be typical for a plumber. Made sure everything worked as it should and then cleaned up after such that my wife couldnâ t even tell work had been done. His prices seemed reasonable. I have him scheduled to replace a water heater soon and just as an example his price is significantly less than the other two bids I got. And Iâ m not sure who it was that called but a few days later a woman called to see if I had had a good experience. Needless to say I answered YES!!"

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.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

If your sump pump has burnt out or malfunctioned before the end of its expected lifespan, you should be able to notice a few warning signs. Running constantly, making strange noises or vibrations, or ceasing to function altogether are all clear signs that your sump pump is due for replacement. You should also replace the sump pump if you notice any signs of incorrect installation.
