"Todd , the owner of at “First Servive LLC”was a 5 star PLUMMER !! When I called him he gave me a quote over the phone when I explained the problem and came out to our home the next day. Our hot water heater was leaking onto the floor and water was only getting warm. He found the problem fast and installed new elements / thermostats in the upper / lower panels on our 50 gallon tank .He checked our whole system and tested it. Todd cleaned up the whole area when done and we talked after in our kitchen for about half hour. He was fast, pleasant , clean , and very reasonably priced!!! I would highly recommend “First Service, LLC. Plumming , for your plumming needs! I now have a great PLUMMER, with only a phone call away!! 5-STAR."

"We were given a complete picture of our basement issues and we relieved that we don't immediately have to do remediation but could deal with the moisture and mold spores by purchasing a more powerful dehumidifier and unit to deal with the spores although we will have to deal with where the water is coming in during heavy rain."

"Had a client in a multi family situation who needed a tremendous amount of existing cast iron replaced in one day. Matthew was hired to remove and replace with new pvc. Got it done in a timely manner so residents would not be down all day and could turn the water back on quickly.Would highly recommended to anyone with all plumbing repairs."

"Our sump pump died Saturday morning and water was spreading. He came within 30 minutes, which was exceptional. He put in a new sump pump that was of higher quality than the one we had, and we are pleased with it. The only drawback was the fact that since this happened on a Saturday, there was an additional charge that was higher than we expected, but his work was excellent."

Water Softeners FAQs, answered by experts

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use tools like Angi’s state licensing tool to verify an installer's license status.

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.
