Thread: Airlifts - pumping water around a gravity system using only air

Unfortunately I am not able to get any of the parts easily.
Even importing from overseas is difficult. The links to online stores you posted for example do not deliver internationally.
But I will find a way.

I doubt you'd lose much pond volume if you did that. And if its all in pressure pipe, once you test them for leaks you hopefully won't ever need to be able to access them again.

One thing I would suggest is to t off from your BD pipes and have purge lines on them both. That is the number 1 way to remove all the muck that settles out in the bottom drain pipes.

Hey just got the app it's a lot better I don't mind seeing the 2 pipes in the corner I'm using slip couplers on the main runs I just think if I ever want to change or incorporate airlifts into the bottom drains or change anything I have the option I was a plumber for 16 years and have seen so many issues with burying pipes it makes me nervous ,I know it's completely normal for ponds but where there going they won't be noticeable and I can easly incorporate slide valves into there's for purging or if I wanted a second skimmer it will add a bit of a option there also I want my water level to be about 5cm below my coping stones so about 75mm from the top does that sound about right I'd ideally like less as my ponds haveing 3 walls round it with shelves and polly carb roof with a roller shutter kinda like a car garage basically but with a shelf all round it about 40cm the frount edge will just have a jump guard across it
