These things<u> cannot handle any pressure at all.</u> The acrylic tube is very thin and will expand under any pressure, the lid and flange will not, so they will crack. Make sure that flow out is equal to flow in or the capacity of outflow is grater then in.
I know this because a little while ago I changed out my carbon and was rinsing it. I stuck the end of tube loosely in kitchen sink faucet ( like I've done 10,000 time before whole holes filter casing) about 10 sec later I hear a loud pop. The faucet wasn't full open, I would have thought that if there was any pressure the tube come out of the faucet aerator.
I know that it's not going to happen with a MJ1200, I would only be worried if some one had a large pump ( say in a sump room in a basement) and it somehow the valve was open full throttle. If you add a valve don't add it to the discharge side.
