Excuse me for adding my 6 pence worth, but John, could you test it out with a lidded bucket with a 4" hole in the bottom. Put your 18000 pump outlet hose through a hole in side of bucket near to the top, lid on tight to stop splashing out, and see if the 4" is adequate to drain. If you have a 4" tank connector and a 90 bend add those and see if it is still ok with a 90 turn.
I am probably way off here, as I have not really worked with these high flow pumps in this situation.
I just had a thought, lol. Maybe best not do it, I can see John scrambling across the floor trying to catch a bucket on the end of a loose fire hose and getting soaked in the process. Don't try this at home.
Steve.

Lol fire hose and bucket. Nice one.
Actually you could be onto something there Steve. He is feeding a shower with that pump which means it will have to pump the water up from say ground level? to say 6ft? where it enters the shower via the spray bar. Now that is going to require a reasonable loss of flow rate due to the head of water it will be pushing so if he runs the pump at something like 70%? he may be close to what he is actually going to be flowing through the shower so may give him an idea as to the size of outlet he requires.

Hey Steve open to all opinions and views and well appreciated.
Good idea and will work,the more I think about it the more I think I will get soaked
18000 ltrs is a fair old whack to be putting in a bucket and as water is cold at the moment,maybe Frim could come up here to hold the bucket for me while I control the pump
Think I should leave it and use one 4ins pipe from bottom to bend then through wall to top of pond.
Thanks for all your help guys and your suggestions much appreciated.John

My initial thought was a single 110mm pipe is plenty.
Did a bit of digging.
CalcTool: Gravity-fed pipe flow calculator
Reckon the 4" would be 3 times what is required, assuming a 10cm slope, play around with the figures they change a lot as the incline changes.
Only way to be sure is pipe it up and find out.Last edited by Simon Fish; 22-02-2019 at 11:17 PM.

I looked for something similar to that the other day for you John but kept getting very strange results when I googled flow from a hard 4" pipe
