head pressure

Hi all I have a hypothetical plumbing question. Let’s say you have two pipes with the same pumps running at 100% The first pipe is 10’ long and is then reduced 3/4” for 1’. It produces 100 gph. So the total length is 11’ The second pipe is 11’ of all 3/4 pipe. Will the second pipe maintain...

Did some searching and didn’t find anything about this. Probably because I’m overthinking this and it’s a unneeded discussion. My 10’x3’x2’ peninsula tank finally arrived. Along with it came a 6’ sump. The DT has an overflow on one side, 2 returns and 4 drains drilled in the overflow...

Hi all, I am looking for some advice on pump selection/plumbing configuration. I am thinking about moving the sump into my basement but I am fairly confident that my COR20 is not going to do the job. I am looking for a minimum of 400 GPH with a guestimated head of 20FT (includes height and...

I need to up my return flow on my tank to match the specs on the uv sterilizer I attached (recommends 1000 GPH/flow). Currently I'm only getting 400-450 GPH. My pump is the Jebao 10000 which can achieve 2400 GPH. One reason I believe my flow is so slow is because all the 90 bends my pvc has to...

Does anyone know the gph loss due to head pressure for the Hydor Seltz D 500 DC pump? I haven’t been able to find a chart anywhere.
