Flow rates are for steel pipe, can’t see that it would be different for plastic pipe.

The water goes into a trough and then is pumped back upto top pond,no filter as only has goldfish with plants.

Thanks not sure of flow rate but I have a badu 14 pushing water back up behind the waterfall under pond to an upstand in the pond which does make a good current.I will upload a video if i work how to do it.
I have a float switch in trough doing auto top up as you lose some water from spray and wind.
Waterfall does need a clean every few weeks with a stainless steel swimming pool brush as aglae does form but it comes up as good as new.
The slate is nailed like you would on a roof but i have put silicone under the btm end and then on all the joints.

Ended up ordering a 110mm bundle from Alternative Aquatics - Spindrifter Aeration Products. Aerated Bottom Drain. Koi Pond Supplies.
Here is my sketch up of the pipes. Decided to bring the pipe up before the red bush and across as it would be a pain in the ass to dig under the red bush

Got my spindrifter, doesn’t seem too robust for something I’m going to bury in concrete?
Should I put some sealant on the inner side just in case?

Uhh, too late... already solvent welded pipes. It’s pretty tight assuming there is welding within the pipe joint. The outside has some sort of glue which seems consistent with pictures available on the net.
I also checked with the supplier;
Apparently they believe this was the best way to do it:
Weld the inside of the BD base and
3 welds on the outside of the BD joint (1 within the joint, 2 around that).
The other way they mentioned of doing a bottom drain is to weld both sides of the pipe joint, however they will have to weld the outside of the BD base. Resulting in a less level base.
I can apply sealant, but not necessary as they believe the 3 outer welds are sufficient.

I would still sealent all them gaps just to make sure.
Then dry test it with water. Before concreteing into the base. In other words stand it up. the pipe and drain
Fill with water. And see if it leaks.
Hope i am not sounding like i am asking to suck eggs.
Just trying to help.
I have a spindrifter. And the workmanship was spot on.

Yeh I’ll get it sealed in the final finish.
Just testing it now, wanted to test the BD as well. Put a bin bag over the top and used the BD liner clamp over it. Not working so well as there are trickle leaks at the side of the bag. But leaks are slow enough to possibly confirm if my joints have leaks.
Also attached a pic of the triple weld on the 110 pipe joint. It’s pretty dry here.
Once the water level drops to height of top of BD, I’ll wrap a piece of tissue around that joint to test for dampness.

Nice one mate. At least you now know.
You can then make it right.
And that will be one big job out the way.

Finally, the pond base is in.
7 hours of mixing 2 tonnes of ballast!

My pond might be finished before my builders come back and finish the extension they started 4 months ago!

Time to get the formwork up for the walls and prep for the concrete walls to be poured.
To mix myself I’ll need about 2.5 tonnes of ballast and 20 bags of concrete which comes to about £170. Considering it took 7 hours to mix 1ish tonnes for my slab, I don’t think i can face doing double that amount in a day.
Shopping around for ready mix, general quotes have come in around £300 for 1.5m cubed. But finally found a decent quote for £200 all in. For £30 difference, seems ready mix is a no brainier. Hard part is to get enough bodies to run 60ish barrow loads across 20 meters and up an elevation of 2 meters from the ground level of concrete truck in 30 minutes!

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