Plumbing
Hi, im in the process of building a pond opprox 4000 gal. This is my plan for plumbing. Im looking for any pointers to improve or remove parts that are not really needed. Plan not to scale as you can see I had a bit of time on my hands!
Cheers

You don’t really need two bottom drains on a 4K gallon pond. If you do then I would think you’d need more than one pump to cope with the flow .
I personally wouldn’t split the returns, I’d have a pump on each return to manage the flow.

My pond is just under 3800 gallons and I have two 20,000 vario pumps, one on each return. So in answer to your question, No.
Stick to just one bottom drain, unless you’re going for nearly 5000 gallons. Save some money.

Thanks for the info. I will have to invest in another one.
The reason im using 2 bottom drains is that the pond will be approx 5m in length.

I would move your skimmer to the same wall as the filters/ returns otherwise your return will just push food straight into the skimmer. If you move it it gets to travel around the pond. You will also save money on pipe work and digging?
My skimmer is on the same wall as the returns, skimmer on the left side and the returns on the right side.
If it’s 5m long and nearly 4000 gallons then it must be quite narrow? If possible try and square it off a little.

If you only have one pump I would move the move the valve on the pump in-feed and put it on the bypass of the heater, that way you can bypass the none heated return in winter and still be able to remove the pump for maintenance as you still have a valve on the in-feed
But I would go for two pumps and split the outlet of the bio

I’d have 2 bottom drains on that deffo, at least.
1 in the middle won’t clear the ends.
You’ll need some puff to run 2 effectively though, 2x30k variables whacked up quite high.

Hi Roy, I am just looking at a setup near exact to what you have just the one 1 x 4" BD. I am just wondering about the 3 returns. My new pond is a raised sleeper and 2.4m x 2.4m. To try and avoid dead spots, I was looking to put 3 returns running along 3 of the sides as per pic below. Was just wondering on that 2" return after the heat exchanger how you are managing trying to get the water to go evenly 3 ways. Are you just adjusting a valve on each one until they look about even? Are all 3 going back in on the same wall or are they distributed? Where mine would have 1 on each of 3 sides, im assuming the different length pipe runs from the bio to the return points may make it tricky to balance the return evenly between the 3?
Cheers

I have 3 returns on 3 separate walls, as for balancing, I basically opened up the valves more the further away the pipe run goes, to be honest I am not sure it makes much difference as long as the water looks to be moving, just my opinion
This was my first drawing of it, although I didn't go for 4 returns and I did it in 2" pipe
