"Jay immediately answered my inquiry and provided same-day service. He thoroughly explained what he was going to do and got the job done fast. His pricing was much better and service was faster than going through the big brand companies. I am incredibly satisfied and will be keeping Jay's card around for future plumbing repair needs."

"Precision installed my water heater two years ago. When I had my furnace serviced, the technician checked the pressure on the water heater and it was very high, a component had failed. A plumber from Precision came out and replaced the defective part since it was under warranty. He suspected that a water pressure regulator may have to be installed but when he checked the water pressure coming into the house, it was in the acceptable range. He could have just as easily told me I needed this and it would have cost me $600 but Jacob was an honest man. I am so impressed with his integrity. I will use them again in the future for sure. The replacement of the defective part didn't cost me anything. Thank you Precision for being an honest company."

"By far the best plumbing experience we’ve had so far in Denver. They came out the same day, didn’t charge a visit fee and provided a competitive no-obligation quote. On top of that, Chris was fantastic to work with, super friendly and took the time to explain each step of the work prior to performing it. I truly feel like I better understand the inner workings of my house after having him out. Fixed our ice maker box, installed our pre-purchased whole house filter, and threw in a complimentary toilet pump replacement. We’ve had several different companies out recently, most far more expensive, one slightly cheaper, but this was the first appointment where I wasn’t handed a tablet with financing options pre-generated. Wouldn’t hesitate to call them again."

"We heard a constant hum from the sump pump last evening and found the motor trying to run but nothing being pumped out. We pulled the plug and called for service. Joe found nothing wrong with the pump. A switch was turned off that should have been on and the outside drainpipe was frozen solid. We had not thought of the drainpipe as we knew the water pumped out a few days before as snow was melting. An unusually long cold spell caused freezing and pitch of the pipe was wrong at the end of the pipe. Joe was very knowledgeable and honest. He got things working again and gave us good information for the future. We will definitely use this business for future plumbing needs. We would recommend them to others. We felt the service fee was reasonable too."

Sump Pump Installation questions, answered by experts

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle. 

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.

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

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.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.
