I have a 15' Intex metal frame pool, with the stock filter/pump. My neighbor recently took down his pool and sold us his pump for $50. The pump claims to do 60 GPM which is a nice step up from the stock pump, the only problem is that it doesn't have any sort of filter with it. I tried to set it up so that the new pump was infront of the Intex pump but the problem was the new one pushes so much water that even with the filter out of the Intex pump it was still popping the top off.
Now my problem is my wife still wants to be able to use the old pump because of the filter, which I can't disagree with. So I have two viable options right now.
1) use the existing skimmer basket hole to drain into the new pump, split the return from the new pump into two lines, one throttled line going into the intex pump and one going into a pvc return and do a spray bar type setup. The Pro to this is no cutting is needed.
2) Cutting a 2nd set of holes in the pool to be able to run both filters. How much of an undertaking is this, what parts am I going to need. what should I know?
I guess I am looking for advice on how to proceed forward from people who have done this before. I should also mention that when I had the intex pump behind the new pump I did NOT have the Intex pump plugged in (seemed logical to me). I also don't think I could put Intex in front of the new pump because I don't think I could enough throughput and am left with the same problem of a weak return.
