WATER SOFTENER DISCHARGES CONSTANTLY TO THE DRAIN
1. It looks as if the seal on the bigger middle piston inside the valve is cracked. Please check this video from the 7th minute.
2. If the seals are not cracked then try to lubricate them and return them back. This may also stop the leak.
3. If you think the seals are cracked and need to be changed then please contact us.
