"We moved into a lovely house with many unsuspected problems including a very wet basement back in Nov of 2017. I did much research to find the best outfit to fix the problem. Ct Basement was not the cheapest. In fact, they were the most expensive by far. But, they were also the yardstick every other company compared themselves to. The job cost us 19,300. And we had to wait weeks for the work to start. BUT, everything went perfectly. As soon as the old debris was removed, I was shocked to find that the garbage of the old walls and flooring they removed had black mold under it. And, with its removal, my wife’s athsma cleared up and left town! They did a beautiful job, were very polite and the new installed basement, new sump pump with back up battery, perimeter trench, flooring, etc., all is great. They put a lot of work and material in to do this job with very skilled workmen who worked very hard. Sometimes you get what you pay for."

"Had a water leak coming from A.C. unit and I called HARP on Saturday morning and was informed a technician could be out on Saturday between 2pm and 6pm. Jaime informed me that it was $89 for service call and $25 for fuel charge and HARP does not charge by the hour but by the job. At 12pm I received a phone call from HARP dispatcher and i am told that the tech finished up his job early and would like to come over to our home, I informed her that we were not home, she said no problem we will see you at your schedule timeframe. Dispatcher called again at 1pm and asked if tech could head our way and I said yes, we were home. Courtney Ivey came out and arrived at 1:45pm, was very professional, personable, clean, wore slippers over his shoes, uniform was sharp looking, wore a mask, provided me with some great helpful hints, turns out I needed I condensate tank pump. He replaced the pump, took the old one away and paid for the part and service. I later saw on HARP website that they offered military discounts, so I called and spoke to a wonderful person named Debbie. I explained that we had just paid for service and was wondering if it was too late for HARP to provide the military discount, she said absolutely we can. She sent an e-mail to HARP billing department and asked I be credited 10%. I have to say little shocked at all the negative reviews. My experience was 100% hands down."

"Great. They called to make appointment. Called to let me know they would be there in 15 minutes, Were on time, professional, efficient. Due to house and plumbing being 50+ years old, they did have to find a part at the supply store but came right back and finished the job. They advised us to get the lower shut off valve fixed in the future and sent us an estimate. Very pleased and would recommend them to my friends.$199"

Sump Pump Installation FAQs, answered by experts

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.

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

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.

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.
