Barrels in the Greenhouse Take 2

boss

I'm unclear what a dual wall Uniseal is. Care to elaborate?

End cap and barrel
So a normal uniseal fitting but the 2 walls thickness
I had to flatten the barrel slightly to get it through and I also chisels the thickness a little thinner

ohh gawd what Id give to have my own land .

Our landlord has given me open permission to do what I want but sitting on granite, limestone and clay...no digging holes for this little black duck. Everything has to be above ground.

1. Nearly finished the frames
2. Enough drop to run 2x 20mm elbows and into the 90mm return
3. Looking back at the door I'm going to out a box step with 90mm fountain pouring out under it
4/5. The sump overflow to be plumbed through the pond liner

I've now finished cutting barrels and finishing the legs and supports.

Just wondering what everyone's thoughts are on...

1. 90mm pipe with 20mm uniseals plumbed in and taps - plumb in from side - for inlets
2. 90mm pipe at the bottom to catch 20mm standpipes returning with elbow then elbow into uniseal.
(does the length of the cross section matter for bell siphons?
3.

Jay I'm not sure on what you mean by "to catch 20mm standpipes returning with elbow then elbow into uniseal", I think that you are saying you want to use Uniseals on the top of the 90mm to take the elbows down into the 90mm. If that is correct, that could cause an airlock, don't use Uniseals on top of the 90mm just bore your holes slightly larger than your elbows.

The length of the cross section on a bellsiphon creates back pressure to cause the siphon to happen, if it's too short or too long you will have problems with the siphoning.

It's all looking good Jay, love the decking :thumbright:

Really? Maybe I need to put some small holes in the pipe or a T and sieve top every now and then.
I didn't want the water splashing back up out the crack or if I pull the stand pipe sometimes it backflows out at high pressure

I had 3 x 1/2 barrels runing into 90mm pipe without losing any water whatsoever, the photo shows the end 1/2 barrel on the run. There was plenty of clearance in the hole size with no lose of water or splashing.

If you do want to use Uniseals you would probably need a breather tube on the 90mm pipe to avoid an airlock.
