Water softener problem caused by the control valve

Continuous drains out from the Drain outlet

1. Water leakage inside the valve body

1) The water quality of the inlet water is poor, and the seal of the valve core will be damaged due to large particulate matter, resulting in water leakage

2) Damage to the rubber ring at the seal is mainly caused by improper installation or maintenance

3) Water leakage caused by cracking of moving plate, mainly caused by freezing or impurities

2. The valve does not act in the backwash or forward wash position

1) The valve suddenly loses power during backwashing or forward washing

2) The water pressure is too high, causing the valve to be unable to operate in the backwash or forward wash position

3) When the valve is in the replenishment position, a small part of the water in the control valve will be discharged directly from the drain for cleaning.

4) The drainage pipeline is too long, causing the piston to not move in place and water channeling. It should be noted that the distance between the drainage outlet and the valve should not exceed 5m

Water channeling at valve station

1. Manual valve (including manual filter valve and manual softening valve), the handle is not turned in place

2. The water quality of the inlet water is poor, and the sealing of the valve core will be damaged by large particulate matter, resulting in water leakage (depending on the location of the damage, sometimes only the water outlet is discharged, and the salt suction port does not channel water)

3. The fixing column of the valve head positioning plate is damaged, resulting in inaccurate positioning and leakage

4. The backwash strength of the filter valve is high, which causes the upper water distributor to rupture

5. The center pipe is too long during installation, which will damage the lower water distributor, quartz sand or activated carbon particles leak from the lower water distributor or damage the seal

6. The back pressure rubber seal of the automatic softening valve is not good or the water inlet pressure is too high, and the resistance between the sealing surfaces increases, so that the terminal gear will rebound after it is in place.

7. There is hot water backflow, which makes the valve scalded

8. Note that the pressure in the water softener should not be lower than 0.2Mpa

Brine tank water overflow

1. Too much hydration

1) The water replenishment time is not set correctly, the time setting is too long, resulting in a large amount of water replenishment

2) The water supply pressure is unstable, resulting in more water supply

3) The control valve controlled by the electric ball valve is used, and the electric ball valve is not closed tightly

2. The water in the brine tank is not completely absorbed after absorbing salt

3. Add water to the brine tank during backwashing

When backwashing, the water outlet and the salt suction port are connected. During backwashing, the water in the water outlet pipe or the water storage tank will flow back to the salt suction port. When installing the water softener of the control valve, it is recommended that the water storage tank and water outlet pipeline Below the control valve, if it is higher than the control valve, a check valve can be installed at the water outlet or a liquid level controller can be installed in the salt tank

Resin loss

1. Resin discharge

1) The upper water distributor is damaged or falls off, and the resin is discharged from the drain during backwashing

2) Resin is discharged during washing or operation, the center pipe is too long, and the lower water distributor is easy to be damaged during installation, resulting in the discharge of resin

3) The drainage current is not well limited, the backwash strength is large, and the value is broken and discharged from the drain

2. The softened water or regeneration wastewater is yellow, that is, the switch produces a sol phenomenon

1) The water temperature is too high or the pH value is too high, beyond the stable range of the exchanger, causing the exchanger to coking

2) After the exchanger loses water, it suddenly expands when it encounters water, resulting in broken
