the waterfall from my spa into the main pool had dropped to a trickle. i assumed it was the pump as it has been slowly failing for the last few months. I just had a new pentair whisperflo pump installed, exactly same model as the old one. i have been in this home for just over a year, the waterfall worked fine when we moved in.
in spite of the change the waterflow into the spa has not increased and i am still only getting barely any overspill from spa into the pool.
when the problem first started i did experiment with the jandy switches (some of which i am not sure what they opened and closed)
the filter (Hayward 60 DE) is not in good shape with a couple of small tears in the panels - i just ordered a repalcement and what look like small stress fractures in the manifold.
is the filter likely to be the problem...
