The jet is formed by a pipe, connected to the pressure side of the water pump, and having outlet apertures with associated jet nozzles. The other pipe end may be sealed, so that the water pumped into the pipe is forced out of the outlets. The pipe is fastened inside or outside the pool, with the nozzles above the water level. The poo filter pump is utilised to pump the pool water, which is returned to the water reservoir, in a circuit.</p> |
