Since I'm new, I hope this is the right place for this. I was given an 18x48 Intex easy set pool. We had to get a new pump because it didn't have the one that used to be with it. This was my grandfather's and he died 6 years ago. Apparently the pump they had on it had a bigger intake and return fitting then this new one. The holes are a tad bit bigger and there are small leaks around the holes. We've tried silicone and some of that rubber flex seal spray, but it doesn't have enough time to set before drops start leaking out. How would I fix this issue because I'm at a loss.
