So im having an issue i was worried about from the start. Often times when i need to pump water out of one of my reservoirs the pump wont work right away. Ive needed to lift the hose up and down and move it around and eventually it will work. With my newest spot, i had to send the waste line really far and up a bit to get to a sink far away in a separate building. The hose itself was dug underground for a portion of it so it cannot be accessed and I need to never have this problem again. The hose is 3/4in and about 70ft long. It goes about 6-8ft up to access the sink. Worked the first time I used it. It hasnt since. Appreciate any insight here.
