"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"pricing for a sump pump installation was on the higher end of quotes however the quality of work and the kindness of the person I talked to and how they fit me in in last minute and they call a few times to verity and go over everything was amazing. I would defiantly pay the little extra for the above and beyond service."

"I had a leaking faucet Andrew was quick to respond. We went over a couple options but i decided to go with a new faucet swap. Andrews pricing was very affordable, he showed up when he said he would he was clean and his work is high quality. I will definitely be using this business again for my plumbing needs."

Sump Pump Installation FAQs, answered by experts

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

First, you can try unplugging the two sump pump cords, one for the motor and one for the float switch, then plugging them back in to reset the sump pump. You can also reset the sump pump by turning it off and back on at the breaker. Many sump pumps have a reset button, which you can press and hold for a few seconds to reset the device.

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.

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.
