    ⭐️⭐️⭐️⭐️⭐️ 

    Delivered promptly and at a good price, Ewen Fletcher

    "I bought the Harvey Series 4 softener as a replacement for an elderly Kinteco that was not working well, together with an installation kit. I was supplied with everything I needed and installation was simple. The Harvey has worked well and I have had no trouble since. I also have reliable soft water once again. I am very pleased that I bought from NE Water Softeners who delivered promptly and at a good price."

    ⭐️⭐️⭐️⭐️⭐️ 

    Excellent product, Paul Phelps

    "This water softener was easy to install as I had the pipework already set up from the old Kinetico softener. Size was comparable to the old softener, just slightly taller with less depth and width. I like the clear plastic cover so the salt level could be seen without removing the cover. Excellent product."

    ⭐️⭐️⭐️⭐️⭐️ 

    Perfect, very quick delivery, Steve Willmott

    "Perfect, very quick delivery. Really easy to install as we were replacing a failed Kinetico unit, which can’t have been working properly for a while as our water is now very nice. So much easier using salt blocks rather than tablets too."
