I have an 8-year old pool, 12000 gal, with attached spa and spillover. After some re-plastering and re-attachment of spillover, our flow over the spillover is occasionally low. This is even after backwashing and with a well-functioning pump.
The interesting thing is that if I touch the front edge of the spillover, the water flow suddenly becomes more smooth and the flow becomes a normal "waterfall." There seems to be some kind of fluid dynamics involved indicated by the fact that there is a subtle and invisible interruption of smooth flow remedied by my physical disturbance.
Any thoughts about cause and, more importantly, a remedy?
