copper mash tun manifold question...

I built a mashtun manifold yesterday and put it in my 10 gallon cylindrical cooler i bought at Home Depot, everything fit fine inside ... but the section of copper i extend out through the spigot hole ends up tilting up at an angle when i tested the cooler with 5 gallons of water (manifold sits on bottom of cooler). the seal leaked a bit. should i put spacers under manifold to raise it? install more o-ring seals? other suggestions?

you got to tweek them to work,for me if I tighten it to much it leaks, just snug it up and its all good. try things till it works.

The output being tilted up should not cause a problem if you're going to connect a hose to it and drain to a lower level. The pressure from your initial volume will start the liquid flowing out and it will create syphon which should empty your tun down to the point where your manifold starts sucking in air.

When you tested, did you use hot water? The heat expansion may have some bearing on your results.

ahh... good point, i used cold. but it was a marginal leak coming through around the cooler rubber seal, the addition of an o-ring or two and the heated wort should probably fix problem? no reason to elevate the manifold with spacers to eliminate the out spout pipe up angle?

no need for spacers because the weight of your grain will press that manifold down.
