"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"Gage has been excellent to work with. We will hire him any time we need something in the future. The work site is always clean, the new install always looks tidy. He has installed a water filter, fixed several leaks in old plumbing, replaced hose bibs, worked on our booster and expansion tank, replaced fixtures. It's always great work."

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

"I got a call from Mike right after placing the request. We set up a time to come out and fix the clog in my tub and he was early. Within 45 minutes he had the clogged drain fixed working properly and gave some professional advice on the drain system. I would highly recommend using them for all plumbing needs."

Sump Pump Installation questions, answered by experts

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

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.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.
