"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.

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.

To get utilities set up on a property, you first have to contact the local department of planning to determine whether your property is able to connect to public utilities. From there, you can work with a structural engineer and/or a building contractor to design the layout of utility lines on the property. The pros will need this information as they begin securing building permits before they can start adding lines.

If your property isn’t able to connect to public utilities, you’ll need to consider working with pros to develop a comfortable off-grid home that will meet your needs.

You can decide whether you need a water softener or water filter based on how your bathing or laundry experience is. If you notice issues like limescale buildup, dry skin, or stains on dishes—all telltale signs of hard water—you'd likely benefit from a water softener. However, if your main concern is over chemicals or bacteria in your tap water filter, and not just comfort, a filter is a better option.

Hard water stains can be a headache because they will reoccur as long as hard water flows through. Thankfully, hard water stains are not permanent. With the right tools and an appropriate cleaning routine, you can prevent hard water stains from ever building up. However, you might feel like you are stuck in a constant cleaning cycle. In that case, you may consider hiring a contractor to perform routine cleaning.
