First I'd check the domes... hoses and pump for leaks.... put your finger over the end of the pump and pump it a few times and see if it holds pressure. a lot of time the check valve in the pump is defective... then check the hose the same way... or check the domes one at a time with one piece of hose... use your mouth to suck the air out.... crimp the hose and see it it holds. if you have an issue with the pump you can go to the pet store and in the fish section pickup some air hose valves..... put one between the pump and the tee connector... pump the air out and close the valve. really reduces the amount of repumping if your system is leak free..
