"Simply PUR recently installed a whole house water filtration/softening system, along with an RO system, in my home and did an amazing job. My experience with Vincent and his wife Claudia throughout the whole process was wonderful. They thoroughly explained the system, the installation process, and answered all my questions. The install went smooth, and Vincent even took care of a flawed plumbing trap previously done. What I appreciated most was how Vincent assured me he would continue to follow-up with me on when I should check my salt levels, change my filters, and if there are any updates with the equipment. I now have piece of mind knowing I'm providing clean and safe drinking water to my family. Thanks Simply PUR!!!"

"From the sales representative, Anthony, to the owners Mark and Madelyn, our family's experience with this company was impeccable. They showed such care and compassion once they found out that the Long Island's hard water in our home caused our 5 month old skin to breakout so badly. She was in such distress and they went above and beyond the call of duty to ensure that the water system was installed ASAP. The installers were so considerate that they even removed their shoes while working in our kitchen, without us asking them to do so. They worked efficiently and were very thorough. Jennifer who handles the office matters, was a pleasure to work with. As she rightfully texted me, It takes a village to raise a child and we truly are blessed to be a part of this water family. We rewashed the baby's clothes and you can immediately feel the difference and the natural products that can only be ordered through the company will save us tons of money from household cleaning supplies to bodywash everything is all natural. I have already convinced my pastors to have the system installed in their new long island home and will continue to recommend this company to everyone I can. Worth every single penny!"

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

Water Softeners FAQs, answered by experts

The most accurate way to determine whether you have hard water is to purchase a water test kit from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

Most experts agree there’s not much difference health-wise between hard water versus soft water. That said, hard water is more likely to cause skin dryness and issues that go along with it, like an itchy or flaky scalp. Hard water can also decrease the life span of your household appliances and make it more difficult for soap to do its job.

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

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.
