"We have some rental lots and we had been using another company for septic/plumbing issues but they have been getting hard to schedule, etc. Called this company today and they were out there within 2-3 hours and pumped the tank for a reasonable price. They also determine there was a clog in the line that needed to be cleared caused by tree roots, etc. They were able to get someone out there immediately and clear the pipe with a pressure cleaner, again for a reasonable price. Fantastic customer service and everything was explained up front. I couldn't have hoped for a better experience. Give these guys a shot because I'll be calling them the next time I need this type of service.

Ohio Valley Pure Water Systems, Inc. has been known around the greater Cincinnati eight county tri-state area for over 30 years for its wholesale pricing and excellent service. What makes water softeners different from each other? \n \nFive things: size, resin, carbon, valve and warranty. \nSize: The amount of resin in the filter bed will determine the size (how often it backwashes) which will determine how much salt and water it uses. For examples, our in-stock water softeners come in a 9x48 32,000 grains (1 cubic foot) or 10x54 48,000 grains (1.5 cubic feet). Other size water softeners can be special ordered. \nResin: The type of resin will determine if it is manufactured for chlorinated or non-chlorinated water. 8% Cross-link resin is formulated for cistern/well water that has no chlorine in the water. 10% Cross-link resin is formulated for the city/country water that has chlorine or chloramines in it. If you use 8% Cross-link on chlorinated water, it will ruin the resin within a year and void your warranty. \nCarbon: Does your water softener contain carbon and if it does, what type of carbon is it, how often and how much is it to replace? Is the carbon mixed with the resin or is the carbon in its own filter housing? The reason you want a whole house carbon block filter is to protect the resin from being damaged which will add years of life to the water softener. It also removes any odor or smells in the water which are NOT removed by water softeners. By separating the carbon from the softener as we do, it becomes cost effective to maintain even to the point where the customer can change their own carbon filter if they choose. \nValve: Is it a timer, digital or metered? The timer valves is the least expensive option of the valves because it backwashes every 2 to 3 days whether it needs to or not. The digital valve is the more expensive because there are no moving parts. When the digital valve has a problem you just simply replace the mother board, which is very expensive. The metered valve is the most popular because it counts the gallons of water first before backwashing. Also, they are very cost-effective to service when you do have a problem. \nWarranty: Nobody offers a lifetime warranty including parts and labor, so don't be sold by the hype. We offer an honest 10-year warranty on everything except for the metered valve. The metered valve comes with a 5-year warranty. The first year parts & labor are included. After the first year, the customer just pays a small service call fee. The only 3 things that can void your warranty are high water pressure (over 80psi), freezing of the water softener and using 8% Cross-link resin on chlorinated water..

"Bought house knowing it may possibly need a water main from the street to the house & without a doubt, complete removal / replacement of all waste & supply lines. With Pauls guidance & expertise we found out that the main was not needed. Wow, there is honesty for you. Paul presented a clearly written proposal on the all the work we discussed then executed the work with professionalism. He was meticulous & detail oriented, kept me informed along the way & did exactly what he said. As a consumer we all make choices. Paul is the right choice. Thanks DC Plumbing !"

Water Softeners FAQs, answered by experts

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.

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

Selecting the right system depends on testing your water to understand the contaminants present and considering your household's water usage and specific needs, such as removing specific contaminants.
