I have one of those Electronic Water Softener/Descalers which has been in use for about 15 years. Recently I noticed the water at a faucet was like soapy or sudsy. It has done this once before and I think it might be from scale in the pipes. The most recent it only did this at a far end from the supply connection. It is connected next to the water heater which is about in the middle of the far end faucet and the supply connection.

Does this Electronic Water Softener have a brand name? Back to you, Tom
