"They did a great job! I knew I wanted a water filter for the house and drinking water since we were moving out of NYC and their awesome water to an area with a crappier water source. And I was about to have a baby! Anyway I did endless amounts of research, including multiple water companies that do their own install, and direct to consumer ones where I could just buy a system and install it myself, and after thinking about it for months (literally), I finally went with QWG. We worked with Maria (who is absolutely awesome) and the cost was reasonable. Between what they offered and how pleasant the experience was, I’m glad I picked them. We have a whole house filter and an RO system that they were able to hang in the basement so it doesn’t take up space under the sink, and it’s hooked up to both a faucet at the sink and the fridge as well. Exactly as I wanted. It’s been a couple months, and the water’s great so far. The support is great too, which is big. Can’t speak for long-term usage yet, but so far we’re very happy! Thank you!"

"Russ of Appliances R Russ is a treasure.he tested and re tested the igniter on my stove top to try to replicate the problem I was having. He showed me the proper way to turn it on. I mentioned the oven door would not close tightly. Russ happily adjusted the oven door. I also told him the ice cubes in the refrigerator were coming out hollow. He went to the water feed -made an adjustment . Ascertained I would need a valve replaced and perhaps a filter and that he would call me when parts are in. HOW refreshing -someone who appears to like his job and wants to make people happy - at least that is my impression. Do not hesitate to call him for your appliance repairs.SATISFIED CUSTOMER........

Water Softeners FAQs, answered by experts

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

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.

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.
