Draining, Re-filling and cleaning cartridges
Over time, water absorbs minerals, chemicals and other soluble materials that lead to an increase in
Total Dissolved Solids (TDS) in spa water, This, in turn, reduces chemical effectiveness, can create dull
water and makes spas hard to maintain correctly.
To avoid this; as a guide, drain and re-fill the spa every 2-3 months, although poorer quality water
may require more frequent draining. For commercial installations, please refer to the relevant HSE
guidelines with regard to draining your spa.
It is advised to periodically, and at least once per year, purge spa pipe work by adding Rotospa Spa
Flush prior to draining the hot tub. We would advise you book a service with us to carry out this
procedure for the best results. When cleaning dirty cartridges, on draining down, it is prudent to
always have a spare cartridge to readily load into the filter housing. This allows thorough cleaning of
the dirty cartridge and for it to fully dry out before being used again.
We advise that you should carry out cleaning the filter cartridge weekly, but more so if needed.
Cleaning should consist of rinsing the cartridge with a high-pressure hose and allowing it to dry before
reinsertion. For a deeper clean, soak the cartridge overnight in a large enough container with some
Rotospa cartridge cleaner. Rinse with a high-pressure hose, again allowing it to dry before reinsertion.
