Check valve with transparent cover for Ø50 / Ø63 mm suction pipe

Description

Main function

The valve is fitted in front of the circulation pump and lets water pass only in the direction towards it. Nothing flows back to the pool, so the pump and the suction pipe stay filled, even when the unit is above the water level.

The problem it solves

If the pump is higher than the water, the suction pipe empties when it stops. At the next start the pump has to prime again, which takes time, and running dry damages the seal and the motor. The valve does not let the water drain away, so the pump primes instantly. Through the transparent body you can see whether there is water in front of the pump and whether the flap is moving.

When it is most useful

• The filter cabin is located higher than the water.
• The distance to the pool is large and the suction line is long.
• The timer starts and stops the pump several times a day.
• After a pause the pump struggles to prime.

Advantages

• Quick priming – the pump does not empty between cycles.
• Pump protection – less dry running and a longer seal life.
• Visible control – the water and the flap can be monitored through the sight window.
• Simple connection – glued to Ø50 or Ø63 mm PVC pipe.
• Access for cleaning – the cover is removed by turning.

Models

Choose the diameter according to the suction pipe in your system; most often it is the same as the pump inlet.

Installation and care

1. Switch off the pump and close the valves.
2. Fit the valve before the pump inlet, with the arrow on the body pointing towards it.
3. Fill the pump and the pipe with water.
4. Check the connections for leaks.

Whenever you clean the pump's pre-filter, take a look at the valve too. If it is dirty or worn, remove the cover and wash the flap.
