"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"I highly recommend this company!!! He responded within minutes of my searching for a plumber. He came the next day and installed a new tankless water heater. He also found a faulty electrical outlet and repaired it as well. Quality workmanship. I will keep his number. His name was Harry."

"Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again."

"Now for the positive experience.  I called Clearwater Plumbing and left a message.  Larry returned my call within 2 hours.  Larry was very pleasant and answered all my questions.  I purchased all the material for replacing two toilets.  I just needed a quote for labor.   Clearwater Plumbing provided a very fair estimate.  I was also able to use Clearwater's coupon on Angie's List that saved me 10% on labor.  Larry scheduled to provide the service two days after I accepted their estimate.  Larry provided a two hour window for their arrival.  Tyler came to provide the work.  He called 15 mins before he arrived.  He wore shoe covers in my house which I really appreciated.  I have changed toilets before but since I had major back surgery my wife does not want me to get injured again.  I occasionally watched his work. Tyler did not waste any time installing the two toilets.  He completed the work on-time per the quote.  Tyler did a professional job and cleaned up the area when he was done.  I would definitely use Clearwater Plumbing again for any plumbing work.  I would also recommend them to all my friends."

"I was very satified with the work done by M&M. M&M determined that my shut-off valves did not need to be replaced, just tighten. After the job was completed we reviewed some other work that I was thinking of doing and eventually hired M&M to complete this additional work."

"There was not much communications between David Carney and the installers. The installers had to come back second time to complete the job and the quality agreed. David Carney has a superior salesmanship. However, after the deposit was made, I was not able to reach David for questions. He did't answer your voice mails and email or going through his office. c"

"Bryson Heating and Air showed up on time! Gave me a reasonable bid. Installed a new unit! Cleaned out my old ductwork and took time after to show me how to clean my unit. Since I live in the country, “we got dirt!”! Joe himself over saw the whole process. Highly recommend! PS Joe also sold me a 25 Kilo Volt Solar panel grid. Saves me over $1000 am month. Solar is the way to go! Anything to save money right now."

"Anthony was awesome. He was early. He was fast. He didn't try to get over on me and charge me for anything that I didn't need. I would hire this company again, and probably will when I change out some other sinks. Great experience."

Sump Pump Installation questions, answered by experts

The cost to repair a sump pump ranges from $400 to $550, depending on the extent of the repair and your location. Minor repairs, like fixing a switch or replacing a float, can cost just a few hundred dollars. However, more significant issues, such as motor replacement or addressing electrical problems, may cost closer to $550. Keep in mind that regular maintenance can help prevent costly repairs, and if a sump pump is beyond repair, a full system replacement ranges between $650 and $1,400.

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.

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

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.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.
