"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

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.

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.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

A good hardness level for drinking water can vary based on personal preferences, but an ideal level is 3.5 to 7 GPG. This means your water isn’t soft or hard. However, some people prefer the “fresh” taste from the minerals in hard water, while others like the smoother, “slippery” texture of soft water.

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.
