Well this hasn't gone aswell as i'd hoped

Been trying to get the irrigation working in my spare time, but it's been a nightmare.

Firstly the kit I have doesnt come with elbows, so I ordered some off Amazon. But it appears I have a 1/4" US system and everything on Amazon UK is metric 4-6mm. The elbows just pop off when the water is turned on as they are too small. I then ordered some from Amazon US marked as 1/4", but even they were too small. Fortunately returning with Amazon has been painless.

Giving up on the elbows I just used the Tee connectors that came with the system, blocking off one outlet to form an Elbow.

However, now I've fired up the system I can't get it flowing properly. It starts to work, but then after a couple of rows air starts to come in from one of the higher drippers Here's a video to demonstrate:

Where am I going wrong. Should I have run it from the bottom up instead?

My thumbs are sore at this point, so thought I'd seek advice before putting them through any more pain.

Well, being a glutton for punishment I rearranged the run so it goes from the bottom up.

Air is no longer being sucked in from the drippers, but I can't get the flow out of all the drippers. About 2 rows (6 drippers) flow, but as soon as I turn on the next row down the water wont reach the highest row.

Water pressure isn't an issue. If I turn the tap fully on it blows the pipe.

I suspect gravity is the issue Whilst the run isn't that long, gravity is effectively making it significantly longer then it is.

I can therefore either switch to a bigger pipe to run up the wall. Or have multiple 1/4" pipes servicing each row or column of pots.

For the benefit of anyone else that comes accross this, the solution was obvious. Supply the water from both the top and bottom

I simply added a splitter on my 1/2" supply hose and then ran one 1/4" supply to the bottom of the run and one 1/4" run to the top. All the drippers are flowing now
