Can they be put into swimming pools?
A few products in the range have been designed to overhang into a swimming pool (LW-003, CAVE-003, MW-002 and MW-003). If these are used, a 40mm water outlet fitting is required as the waterfall is hooked up to the pool pump and needs a larger outlet to accommodate the pressure. Ensure that the pump is turned off when using shock treatment as excessive chlorine can bleach rocks.
