He took the time to answer all our questions, made sure everything was set up perfectly, and left the workspace spotless. You can tell he takes pride in his work.

"Had a big job of 4 water heaters in four different units. Platinum Plumbing blocked off the entire day to get them all done at once. They are friendly, professional, and when it comes to water heaters, very fast. I would highly recommend them to anyone who is looking at having their water heater replaced. I will use them in the future for other plumbing needs should they arise. Thank you!!"

Water Softeners questions, answered by experts

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process 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 Angi’s state licensing tool to check an installer’s license status.

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.

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.

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.
