Pipe Size

[ShanGo]

whats the best size pipe to use as i am useing 32mm and its giving me problems do a go down a size to get the flow right as i have two screens and a 6000 lhr pump

I always try and follow the guidance from the pump manufacturer / pipe size that fits the adapter that comes with the pump. I have only 1200lph going through 25mm and it seems pretty well used - I would have thought 32mm or bigger for 6000lph but I've no experience of that level of flow from a pump

hi shango
i have two screens that are feed by two durso pipes , there 32mm , the return pump is a ocean runner 6500lt but its no way big enough iam only running one screen the the gate value on that is thorttled back so going to use a bigger return pump http://shop.ebay.co.uk/?_from=R40&_trks ... Categories this should do it , just think of the water that will flow down the pipes when the gate values are open full .
