  Nathan BallardAug 12, 2025
  If you notice a continuous flow of water to the drain in your First Sales Water Filtration System, it could be due to several reasons. First, check that the electrical outlet is functioning, as a loss of power during regeneration can cause this issue. Also, verify the timer programming. Debris in the control valve or an internal leak could also be the cause; in these cases, disassemble and clean the control valve, or replace the seals and/or piston. Finally, a faulty drive motor can also cause this problem, so consider replacing it.

Why is water colored from the tap with First Sales Water Filtration Systems?
- M
  Melody BarnesAug 20, 2025
  If the water from your First Sales Water Filtration System is colored, it could be due to several reasons. It might be a leaking bypass valve, in which case you should verify that the bypass valve is in the service position and inspect the seal, replacing it if needed. Alternatively, there could be an internal valve leak, requiring you to replace the spacers and seals. Another possibility is that the distributor is not seated properly in the control valve; ensure the distributor tube is securely seated in the control valve body. It's also important to verify that the actual water usage flow rates do not exceed the system specifications. Finally, insufficient backwash can also cause this issue, so increasing the frequency of backwash might help.
