Ernie,
The "trouble shooting" section, page 5-6D, for the door sagging problem states the test of the thermal relief valve and the lock out valve should hold test pressure for 10 minutes and door test pressure should not bleed down. I use 10 minutes and test to 20 minutes. For your info I also just recently had a red light(same as gear up/down lights) installed next to the gear down light in order to monitor the pump on condition - the light is on when the pump is on. The pressure switch is supposed to turn off(works only in the door closed condition, otherwise the pump runs) at approx. 1500 PSI and on at approx. 1100 PSI - page5-53.
