Returns Flow Control
Hi all,
Is this an acceptable way to split a return from a skimmer line via a sieve and a 20000 litre variable pump?
I haven't shown all the isolation valves at pump and sieve and skimmer etc.
The ball valve at the bakki is always fully open and I control the flow rate to the bakki by adjusting the amount of flow allowed back via the ball valve situated at the below water direct return?

Looks ok to me Ruffers but maybe better useing 2ins pipe at least for the bakki.
1.5ins is ok up to 10000 but better with 2ins with a 20000.John

Thanks John,
It would be a bit of a job to change all the 1 1/2" pipe now maybe an upgrade for next year?
I could if it would it would help use 2 inch pipe from pump exit then split via a Y fitting rather than a straight T?
Then through 2x swept 2" 45 elbows reduced to 1 1/2" to both returns?

It will work ok with 1.5” yes, but would get a better flow for less electricity and wear on the pump if you used 2”.
A Y split is better than a T for reducing resistance.2016 new 6000 gallon pond

Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
