"Well I would beware if you wanted to get a quote from these guys. I needed to get a new well. I received 3 quotes from different sources. These guys came in the best. First I signed the contract in late June and did not get the well till Early Sept. Took an awful long time. They blamed it on weather but there were plenty of stretches of nice weather. No excuse. Then when they finally did complete, the sent me a bill for over $1000 more. Again no excuse. They said they had to do more work so it cost more. Then they need a new estimator who knows what they are doing. I could see a couple of hundred off but not $1000. BEWARE!"

"Excellent work. During the course of the original job (installation of a sump and sump pump), the workers encountered badly corroded drain pipes from from the kitchen stack out to the main stack. Replacing these was a lot of extra work, but it was accomplished quickly, done well, and at a fair price. I highly recommend them."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Sump Pump Installation FAQs, answered by experts

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.

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.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Every three to four months, you should clean any dirt and debris off of your sump pump. You should also check the inlet screen (at the bottom of the pump) to make sure that it isn’t blocked. On top of that, you should deep clean your sump pump once per year—or hire a sump pump pro to do it for you.

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.
