yes I believe most if it is the pump can't handle the demand. it should have a higher volume pump put on, that will be in the works for this year

I'm thinking it might be the OTHER way around, that is, the pump comes up a huge restriction when you use the hydro, and the bypass in the pump is either too high pressure, or can't bypass ENOUGH volume, so the pump is trying to work against high head pressure
