"It went well. The plumber was on time, kept his word, had to come back - showed up as promised; not inexpensive but we were expecting it to be more based on an earlier assessment by a different plumber."

"Great job. Anthony did a complete review of the house and the current venting and recommended the proper size for the AC. The installers and electricians came 3 days later, did additional wiring and piping and installed the entire system in 5 hours."

"They said that they would be at my place between 8-10am. They showed up at exactly 8am!! The technician answered all my questions, he kept me informed as to what he was doing. We chit chated, he was very respectful to a senior citizen (me!!). I plan to hire Plumbing Pus every time I need the plumbing worked on and I would recommend them in a heart beat. Wonderful customer service!!!!!!"

"I called several popular plumbing companies to replace an old dripping shower/tub faucet in the guest bath. All wanted to use their fixture and cut the shower tile to fit the new fixture, so I gave up. After a year or so, I joined Angie’s list and found Top Notch plumbing. Gordon had some fixture recommendations, but allowed me to purchase my own fixture that was compatible with my current installation. The overall install took about 3 hours. Gordon took care during the work to not damage any existing tile or carpet. He knows his craft and performed a very clean and professional install. Overall, I highly recommend Top Notch plumbing and will be saying goodbye to the popular TV advertising plumbers. Thanks Gordon!"

"The plumber showed up on time and was very pleasant and professional. He completed the job in approximately 1/2 hour which I thought was amazing. He took all packing materials with him and left the counter spotless. He did not try to oversell me any additional items over and above the work I asked to be performed. I would definately use Vista Plumbing in the future."

Sump Pump Installation FAQs, answered by experts

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.

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.
