"Absolutely fantastic service!!! Jason did an amazing job installing our new tankless water heater, and the whole experience was smooth and stress-free. 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. We?re beyond happy with the results and grateful for the excellent service"

"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

Drinking hard water is not known to have any negative health impacts. Using hard water can lead to dry skin and hair, and the minerals in hard water can build up in pipes, faucets, and appliances. Hard water is more of a threat to your plumbing than it is to your health.

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.

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.

Hard water doesn’t hurt, but it might feel more abrasive, especially if you have sensitive skin. It’s also about how your skin feels after bathing. You might feel as though you have a sticky film over your body because you do—it’s all that soapy residue left behind because the hard water can’t rinse it off completely.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.
