pressure, it is recommended to use a hydrostatic valve . When there is too much
pressure it opens and removes the water through the main drain.
- To avoid leaks from the pool ensure that the pipework is perfectly joined, and in the case
of concrete pools, there must be a depth of 15cm of concrete all around the main
drain. In prefabricated pools ensure that the main drain-seal-liner-seal-framework is
perfectly aligned and tightened with the corresponding nuts.
