So, I've had my above ground pool for about 2 years now and I am still feeling like a total noob. My pump was leaking, my sand filter had a leaking multi port valve and I decided I was going to switch to a cartridge filter. I bought the following cartridge filter system with pump:

Hooked it up using the existing flexible hosing, all look well until after about 5 seconds the return line flexible hose starts leaking pretty badly. I swapped it out for some of the flexible hosing that came with the system and find that the hosing just barely slides over the barb on the inlet side of the pool. I believe this is a 1.5" PVC barb connector. So I hook it up, crank down the clamp onto the hose, start up the pump, and the hose blows off the side of the return inlet.
I found some different 1.5" flexible hose that I bought last year, it too barely fits on the barb and even when the connector is quite secure within seconds the return line blows off of the barb.
I spoke with someone at work and he said I am probably not going to solve this problem because the water pressure coming out of the cartridge filter is much higher than the sand filter and it is just going to keep happening. I made sure the pump was the same power as my previous pump (1 HP) but obviously the flow seems to be much higher with the brand new cartridge filter vs. the older sand filter.
Any suggestions? Should I try different hosing? Is the barb connector on my inlet non-standard?
Thanks in advance for your help
