Hydrostatic valve for AstralPool sump
4/5
- Hydrostatic valve for installation at the bottom of AstralPool 01466, 27837 and 27839 drains.
- For assembly in conjunction with drainage tube code 21581 (see related products).
- It is advisable to connect a hydrostatic valve and a drainage tube to the drain to relieve the pressure that any groundwater may exert on the pool basin.
- The hydrostatic valve prevents this risk by allowing this water to enter the pool in sufficient volume to relieve the pressure on the pool shell (and preventing it from escaping thanks to its retention function).
- Its installation is recommended in pools built close to the beach, rivers, lakes or on land that is susceptible to flooding after heavy rainfall.
- Compatible with AstralPool drains with codes 01466, 27837 and 27839.
- Made of white ABS, with stainless steel screw and spring.
- 1½" male thread connection.
