So I just finally got my pool up in the back yard. As my signature states, I installed an Intex Ultraframe Rectangular 32 x 16 pool and my family is loving it. My problem is I purchased the Intex Deluxe Maintenance Pool Kit which has the 1.25 inch vacuum hose and head with it. The sand filter pump which is 2650 gph appears to run dry when I try to use this vacuum. I prime it and remove all the air and after it runs for about 10 seconds it does this weird bubbling thing and sucks in air. Is the problem due to the fact the hose is undersized for the amount of suction coming from this pump? If so, could the situation be rectified with a 1.50 inch hose? Just trying to understand what would cause this issue before buying any other equipment. Any suggestions would be greatly appreciated because the floor of the pool is fast becoming littered with various types of debris.
