The drain loop consists of two drains that are connected internally in front of the drain solenoid valve (SV). After the SV, the overflow loop is connected to the drain loop and, from there, to the drainage system via the water seal described above, which was installed by the installer.
When following a continuous water filling process, the hot tub has an overflow loop composed of 2 overflows that are located above the height of the telescopic filter. They discharge the excess water into the building’s sewage system after it passes through the siphon, regardless of whether the SV is open.
