Comments/Observations:
On float was out of order at the time of inspection,replaced the float and all floats are now operating correctly.Flow rate was high at the time of inspection,the
reason was determined to be a cracked gasket in the zone return valve,replaced gasket.System's water level after repair was too low to be able to test new flow rate.
