Hi,

I have a pond with a bottom drain and an adjacent cellar. Are there
any filter systems that can be below ground level (and below the
level of the pond water) and fed via gravity (ie bottom drain).

Thanks,

Sky
I suppose you could put a pump after filter to move the water back up to the
pond. Not something I'd ever consider........faulty pump equals full cellar,
empty pond. ?
