"Simply PUR was a pleasure to work with from start to finish. They were personable and provided us with a lot of information and answered all of our questions. The installation process went smooth and they came back to check our water filtration systems and retested my water. They were honest and sincere and most importantly very reliable and professional the whole way through. Its always a pleasure dealing with Simply PUR. I highly recommend using this company and will continue to refer my friends and family to use them."

"Jose and his team were super professional and very knowledgeable. Not to mention honest. Needed my whole house filter changed and ended up adding on a purified water system for drinking. The whole process was seamless. I would definitely recommend them to anyone looking for an honest and reliable company."

Water Softeners questions, answered by experts

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

The most effective way to fix hard water in your shower is by installing a whole-home water softening system. This system treats water as it enters your home, removing the minerals that cause hardness before they can reach your shower or any other fixtures. While this is the most comprehensive solution, other methods are often temporary fixes. For a more affordable and shower-specific option, you can install a water-softening showerhead or a shower filter. However, these filters are generally less effective and may not remove all the contaminants that lead to limescale and hard water stains. By implementing a water softening solution, you can expect a reduction in mineral deposits and enjoy the benefits of cleaner-feeling hair and skin.

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

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.
