The lid seal for the QS 400 filter tank is a key element ensuring the watertightness of the joint between the tank body and its lid. A damaged or aged seal causes water to leak under pressure, a drop in filtration performance and potential damage to the surroundings of the plant room.
The seal is made of a material resistant to pool chemistry, UV radiation and the temperature fluctuations typical of outdoor operation. The precise dimensions guarantee the correct fit and perfect sealing of the joint without the need for additional sealing material.
We recommend replacing the seal whenever winterising the pool or changing the filter sand. It is inexpensive preventive maintenance that protects against unplanned repairs and extends the overall service life of the QS 400 filter tank.
