Well this morning I ran the slides out and back in then closed the 4 valves for the slides. 4 Hours later I could not push the slides out and the fluid level in the reservoir was the same as when I first retracted them. Then I opened the valve for the dining room slide and checked the reservoir fluid level about an hour later and it had risen about 1/8 inch. I then opened all the valves, ran the slides out and back in and closed all the valves except for the entertainment slide. When I checked it 2 hours later the fluid level had again risen in the reservoir. Throughout the rest of the day I repeated this cycle for the other 2 slides and each time the fluid level in the reservoir rose. So it would seem to me that somewhere between the shut off valves and the pump the system is losing pressure.
