Deep cleaning sand filter INSIDE a pool shed

[SgtWilko]

Does anyone know of a « bib »-like device I can strap around a Hayward S244T sand filter to be able to deep clean the filter inside the pool shed where the filter is located? Something I could hookup a suitable drain hose to, to direct the water outside the pool shed. Hauling the filter out without emptying it of sand first (300lbs) is not an option. Emptying the water and sand to do so would make the whole process ridiculously labor and time consuming (Drain, empty sand, take out, refill sand, deep clean, drain, empty sand again, haul back in shed, refill with sand… ). I might as well just change the sand if that’s the only option.
I can hack the drain line connection easily but a suitable and realistic « bib » eludes my imagination.
Any suggestions appreciated.

I recall others in the same situation and they fabricated a make-shift water tray around the base of their filter. Sane concept as a safety tray around your water heater, just larger and customized based on materials you have available.
