Screen pipe size

[billy mitchell]

I have been looking at what has been written on scrubbers and would like to know if there is a difference with using a different size pipe to hold the screen
looking at some scrubbers seems they use 20mm to house screen
would there be any benefit in using a 25mm pipe (I have all the fittings to use 25mm but I can reduce down to 20mm if I have to)

Not much difference really. Bigger is probably easier to cut the slot.

I have always used the 20mm-3/4" but 25mm-1" should work fine too but you might need to increase the GPH a little over 35gph per inch maybe.
