Here for sale is a brand new set of seals for many WinterHalter / Kinetico water softeners that will suit many models including the 2020c, Compak, MonoMatik, DuoMatik softeners. If your unit isn’t functioning correctly such as slow to regenerate, failing to complete regeneration cycle or losing water through the brine waste etc then your seals are very likely to be worn out. This kit comprises of 4 main piston seals, 4 main piston shaft seals and 3 control valve piston seals. ALL of these seals when in operation slide against plastic surfaces with water as there lubrication so they wear out and once worn the softener can give you the impression it has failed but all it needs is these seals replacing. With these seals comes a satchel of silicon grease to lubricate the new seals and allow your unit to continue many more years of active service. The seals are relatively easy to replace and I can provide support or can be found on YouTube. However please see the additional photos I have placed on listing that shows where they are all located on a dismantled unit. The first 2 pictures is the seals listed in this item and the additional pictures are for reference only and not the items included in this sale. In my many years of experience these seals will fix 95% of water softener issues but if not sure please message first with symptoms and softener model. These seals can be fitted in around 30mins. You will require delicate hands and a few tools such as a 5/16 socket, a small pick or small blunt screwdriver to complete. Buyer welcome to collect or happy to post. I have sold many of these kits and received success for around 95% of my customers. Please ask any questions as happy to help.
