The vast majority of sump tank set ups i've seen on line have a system where the display tank is double drilled, one for drain and one for return, makes complete sense yeah? My set up seems to be in the minority because my display tank is only single drilled and houses both drain and return. Don't get me wrong it's working absolutely fine but it could be a problem with the next step i want to take.
At the minute i've got a soboWP6000 pump which is meant to give a max of 4000 lph turnover (obviously this is reduced due to height, pipework length and elbows). What i wanted to do was get a soboWP7000 which is 5000 lph turnover just to give me a little more water turnover. I'm thinking that because my return line comes up through my drain pipe that the return line is inhibiting water flowing down the drain, obviously. My question is, am i better sticking with a 4000 lph pump or, if i increase my pump capacity do i run the risk of overwhelming my drain pipe thanks to the positioning of my return line on this set up?
