"we hired traditional plumbing ( john) 4 times now, and one of the 4 times was recently, to do various projects for us. We had quite a list for him, and he did an excellent job. One of the projects was to get our main water shut off- to work. It was old, and corroded and frozen. He had to call our city water dept, and have them come out to go into our lawn, to find the main valve out there, to go down 6-7 feet, to shut it off. While the city was doing that, john went to a supply store to pick up the necessary parts he would need to fix it. John then made the necessary repairs, putting in new parts, and he did a great job. He also put in a new dual sump pump that we had purchased- ( he helped us to find a good one-) basement watch dog, and so, we asked him to put that in for us too. and he hooked up the battery for us, and showed us how it worked- plus he also made a new shelf for that battery to sit on, above the sump pump. We also had him install a new vanity top and faucet we had previously purchased, and then also we had him unhook an old water softener for us, and cap the pipes. We also wanted him to put on a new turn valve ( which got broken) on the pipe for our toilet. He really did such a good job, and we are happy that we found him through Home Advisors. He is a very nice man, and his pricing is fair too. We would recommend him very highly."

"When I called, because we were looking into a new furnace and air conditioner, Cardinal sent Rick out to check things out in our basement and outside. My husband wasn't here the first trip out so Rick came back to explain what our options were to both my husband and myself. He explained what qualified for tax credits and rebates and then any add ons for heating and cooling. He explained what a heat pump was and how it worked. Then he shared his experience with the product. It was so nice, he came over on a holiday weekend, never pressured us, or was impatient, just a down to earth guy who really wanted to give us the most information to make sure Cardinal would meet all of our needs. They definitely did. Two days later their installation crew arrived bright and early and were done by early afternoon. The house felt different immediately with the in home humidifier and April aire system installed. What a difference! Thank you Cardinal for that wonderful two fur deal!"

"Mickey, our installer, was professional, knowledgeable and friendly. He even took time to help reattach the discharge hose when the installation was completed. I did find some small stones and debris in the corner after he left. Likely from the old sump pump. I chose Blau without doing a lot of comparison shopping. I asked for a breakdown of material costs and labor costs. But was told they only provide installed cost estimates. After some further research, I now feel I could have gotten a lower price elsewhere, but I am satisfied with my purchase. Cheapest is not always the best."

"The project began on schedule and was completed before our move in date; and was coordinated well with our other contractors; ie: flooring and painting.
In the middle of the project our basement flooded due to a failed sump pump and significant snow melt. John assisted arranging a pump replacement and worked with the cleanup crew to get things back in order.
When John and I were not satisfied with the work of the dry wall subcontractor, John replaced him and redid some of the work."

Sump Pump Installation FAQs, answered by experts

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.
