I am having a beast of a problem with with my holding tanks. You know the normal three tiered systems with a sump underneath. These are older systems and they came with 1" drains and 1/2" returns. My problem is that my pump is to strong and they systems arent receiving proper flow. The 1" line is to slow. The layout is basically a straight line. I have a 1" T coming off the tank and running straight down. Where it meets another T on the second and third tanks before the sump. Can i replace the Ts with a 2" line and get more flow. The bulkheads are 1" and i cant change that. So what i want is to get a 1" x2"T and run that. That way the 1" line will not be hindered as much. Will this work?
