"George and his team were extremely friendly and professional. This is a good group of people. Courteous and thoughtful, they were able to do a complete installation of both systems from scratch in about 6 hours.
The new radon remediation system (Bubble Up) has the added benefit of boosting the fixture pressure in the house to city level or better (60-75psi) as well as completely resolving the pH level of the water.
The cost was slightly lower than the other two quotes we received, partially due to the fact that Absolute offered a "multi-system" discount since two systems were going in at the same time.
If in your service area, I would highly recommend George Doumit of Absolute Water System.

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"We were so happy with the kitchen and master bathroom remodel that Todd did for us that we hired him again to remodel our downstairs bathroom. Todd gutted the old bathroom down to the studs and rebuilt the floor in order to remove water damaged boards from a prior leak as well as accommodate the new curb less shower pan. Todd was very thoughtful and had some good design & layout suggestions and helped us work thru other challenges like how to route/hide things we didn’t think of such as vent pipes. Todd found and installed new window trim and doors that also closely matched the rest of the house to help maintain consistency throughout. He installed new tile on the floor, shower walls, and subway tile halfway up all the remaining walls. All of the lines were perfect again and he did a fantastic job. We have received many compliments on the bathroom and are thrilled with how it turned out. Todd is a pleasure to work with and we highly recommend him and his work."

"Rick responded immediately to my e-mail inquiry through the website and called me to set up an appointment.  He was extremely professional, courteous and knowledgeable.  As it turns out, after making the arrangements for the sump pump, we discovered the source of our water was from our heating system.  When we informed Rick of this and the fact the sump pump would not be needed, he promptly refunded our deposit.  I would definitely recommend Rick Jackson and will contact him in the future if the need arises.

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.

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.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

A sump pump's lifespan is typically 7 to 10 years, though the general range can be anywhere from 5 to 15 years. The specific type of pump is a major factor: pedestal sump pumps last an average of 20 to 25 years, whereas submersible sump pumps last between 5 and 15 years. While pedestal pumps are less expensive to service, they are also louder and more prone to clogging.

Several other factors influence longevity, including the pump's quality, usage frequency, and maintenance schedule. A high-quality pump that is well-maintained in a dry climate may last for two decades, while a lower-quality, poorly maintained pump in an area with a high water table or frequent flooding may fail in six years or less.

Regular maintenance, including annual inspections and tuneups from a professional, can significantly extend the pump's life. It is time to consider a replacement if your sump pump runs constantly, cycles frequently, shows visible rust or corrosion, or trips a circuit breaker. As a preventative measure, many homeowners replace their pumps every eight years. It's also worth noting that a manufacturer's warranty can indicate expected lifespan, and some home insurance policies may not cover water damage from a pump that is past its recommended replacement date.

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.
