Siphon break question
Graham, the set-up you''re describing is commonly done...and when the siphon break prevents the pump from working well (after all, it IS breaking the siphon...) then it''s either removed or defeated. You want the siphon break on the INcoming line to be between the pump and the bowl. That way the pump is not affected, yet the pump can''t feed the bowl and overflow.
Obviously, the other siphon break is downstream of the pump. Both breaks should be mounted above the dynamic waterline, meaning as high as you can get them for ease of mind.
A solenoid will make things even MORE complicated. You''ve already done this by virtue of using an electric head; no reason to compound the problem further.
