The reason it takes forever to get the air out is because most folk foolishly try and fill / bleed all the loops at the same time with the manifolds on. If air is getting in that way il donate my next donut. The pressure differentials here would just see mains water squirting out. Bernoulli says it'll tend to suck air into the pipe. If water is flowing past an opening in a pipe, Herr Prof. If there's a drip, there's an opening to the atmosphere. If I read your post correctly, you're filling/flushing the pipework from a garden hose that's dripping. Next time it gets the pressure released will be for the pump and buffer to be fitted so I'm not going to get too worried about the water in it not having antifreeze or inhibitor in it - I've calculated the buffer and loop capacity and will just make the concentration up based on that and wait for it to naturally mix which will only take a few days. Mines been sat at 1 bar for 4 months now and tbh it's never moved. You may find the pressure valve connection on the manifold leaks slightly (mine did) so just watch for a weep there. Once you've got each loop clear then open them all half a turn and run it for another 2-3 minutes before closing the drain - you will watch the pressure rise in the manifold, take it to 3-4 bar then close the hose connection.Īt 3 bar any leak in a pipe will be easy to see. It can take 2-3 minutes per loop to get the air out of each loop. Close the valve and move to the next one, again running to a hose and letting it run clear. and let the water run - it will spit and bubble but let it run until it's pretty clear of air.
#Manifold garden looping full#
Open the manifold drain half way and then open the first loop full bore. That will show you any leaks in the manifold. The correct way is to put the hose onto the filler connection, close all the loop valves and the drain valve and then turn the hose on. Hoping some other experts can advise! TIA! I'm hoping the air is being introduced elsewhere - could that be the case?ĭoes it matter that I may have some air in ufh pipework when the concrete gets poured? I presume as long as it is all under pressure then I should be okay? The air can be expelled at some other distant point I presume. Certainly no leaks in the ufh pipework (had a visual check in the rooms done so far). I won't have a pressure reading until I have water in all circuits so can't yet determine if there is a pressure fall. Is it possible that the air is being introduced into the ufh set up, rather than within the ufh pipework/manifold? No sign of leaks in pipework yet. Have had to rig up a temporary water supply to the manifold from an outside temporary tap involving a longish hose pipe and there are a few drips along the way to the manifold supply valve (i.e. As concrete is being poured tomorrow first thing I'm feeling a bit anxious. I have started to bleed my 12 circuits and am finding that there is a lot of air being dispelled in the bucket (had to empty about 6 buckets on one loop already).
It's not too hard to return to the normal stairwell.As usual, things are turning a bit last minute. Even looking at the level design from an unintended perspective which breaks part of the illusion, I can't tell how it works! I can go to the stairwell and walk just past the floor, which allows me to see the intended looping area inside the stairwell. Above me is what looks like white empty space, and if I fall into it I get warped to a similar area but with the floor below me again (so I fall safely and don't outright escape the level), which seems to be on the other side of the intended playing area. I found a way to slip between the floors:įor whatever reason, walking down/up the stairs like that allows you to bypass some of the warps, which means you can get to this strange place: The problem arose when I decided to walk on the ceiling in the stairwell. The hidden path leads to an infinite stairwell, which leads to this room in the middle through four doors, which has one intended exit that I could find. So, I opened a Hidden Path which sent me to an earlier stage, and I wanted to backtrack further but couldn't remember where to go it seemed like I was in a dead end.
