volume washers......again

[davidroberts30]

im setting up a washdown system here and need to take the water 50 meters from the tanks and pump to where the washdown hose will be

i was hoping to be able to use about 25meters of 25mm washdown hose to reach all the yard, so potentially 75meters of pipework

a few years ago i dropped a 32mm alkathene in for the purpose but only now getting to set it up


is the 50meters of 32mm big enough with 25meters of 25mm hose or do i need a 50mm pipe with 25mm or 32 mm hose on?

will call into allpump later on to see what pumps they got but they are offering a jet 251 pump set

50mm would be best, Allpump will give good advice.

I found a online flow calculator earlier that basically says if I want flow and pressure I need to go 50mm

We have two hoses in our pit that are both fed from the same 50mm pipe from the pump. The one at the bottom end of the parlour is only 20m from the pump but the one and the top end would be nearer 50m and has significantly lower flow even through 50mm pipe.

I've a few scraps of 63mm I was gonna use as the feed to the pump
