Does this look normal? This is a shot of the beckett injector. That's water shooting out of the holes in the side of the injector.
if you put a couple of wraps of teflon tape on the top and bottom of the injector, where the rubber bands are holding the casing together, it should stop that. it also helps stop the beckett from rattling, something else that will happen occasionally.
i've stopped doing the tape trick over time, none of the problems it solves have anything to do with the proper functioning of the skimmer, and i find that i'm more likely to clean the injector when it's easier to do the maintenance.

SDguy et al,
Just to be clear about the 90 slip going into the injector, in Newsalt's picture, the 90 slip/fpt fitting is glued into the black injector flange?
Thanks

SDguy,
Thanks again for the info.

OK I am new to this thread and I have a few questions. I have a MR4R and I located it higher than my tank and my sump. I have the water draining from the skimmer down to the sump. The line is probably something like 14ft. Is this a bad way to run my skimmer? Also the drain runs right out of my gate valve to a downward position, should I have a T at that point? I get a ton of bubbles so I run the return into a filter sock to eliminate them.

elvictre, it won't affect your performance if the waste runs to your sewage, but it will make it impossible to have the skimmer "shut off" if it experiences an overflow episode. you don't need one of the auto-shut off collectors, just have the skimmate drain line go into a bucket stopping a couple of inches from the bottom. when the skimmate in the bucket gets higher than the drain line, it essentially shuts off the air flow through the skimmer and it stops generating foam.
i defeated bubbles two ways on my wee little MR-1. a great mod you can read more about in this thread is to shove a 90 degree slip fitting onto the output of each becket (in the skimmer body) to redirect the flow to the tower instead of the drain line. i'm not sure how the recirculation affects this, someone else can chip in if this doesn't make sense with this configuration, but i don't think it'll make a difference. the other way was to have the output go to a 90 degree elbow at the waterline of the sump, having it under water creates backpressure and having it above the water creates more bubbles, so pretty much split the difference.
with a 14' drop to the sump, you may need to take some more extreme measures, like put a T after that 90 so air can vent from above.

I agree it is not a good idea to have the waste going into a drain. Best case scenario if it overflows the skimmer you burn a pump or two, worst case if you have a auto top off, well, you know...

OK I have been struggleing with my MR-6R for 6 months now and hope someone can't give me some suggestions. I am feeding it with a Mag-7 and the recirc pump is a Baracudda Seq as recommended from the MRC website.
Initially I had one heck of a time trying to set the water level and bubbles as the instructions were pretty generic and did not tell me that I needed to set the water level much higher than recommended. I also had the air valves opened up all the way and turned back 1 turn (as recommended). I had a very hard time keeping the foam level consistant and most if not all of the skimate just sat on the walls of the upper portion of the skimmer.
A few weeks ago someone recommended that I open the air valves ONLY 1 turn instead of being almost all the way open. I had to raise the water level MUCH higher to do this, but the foam level became very stable and I was able to start getting some skimmate into the waste container. I started to think my problems were solved.
2 nights ago the power went off for a few hours due to a storm. I turned of the recirc pump so that when the power went back on I wouldn't have any sort of overflow as I know that turning on and off the recirc pump can cause some water to come out of the air values. What I didn't realize is that the water level in the skimmer was at least 6 inches ABOVE the air valves. When the recirc pump is running that does not matter. When the power came back on (3-4 hours before I woke up), apparently I had a nice steady stream of salt water flooding my room.
After playing with some settings, I have now come to the conclusion that it does not seem possible to have the correct air and water levels on this skimmer 'out of the box'. I think the only solution is to raise the level of the becketts. Can anyone that has an MR-6R confirm this or maybe help me find what I am overlooking?

Randy, you have a PM
Open up the beckett housing. Remove the black backett. Slide off the small rubber gaskets from each end. Open the two halves. Dry everything really well. Then superglue the internal arrow thingie (actualy word
) to ONE SIDE ONLY (you'll see where it actually touches the beckett casing halh at only two points). Let dry. Replace the two halves together. Slide the gaskets back on, and place the beckett back into the housing.hth

Thanks. That problem is solved. The next problem I'm having is the water level in the main column changes from time to time. I usually keep the bubble/foam line at the top flange. That usually works great. After a few days, the bubble/foam line drops to middle of the main column. What could be causing this? The outlet of the skimmer is not submerged in the sump water. I find that I have to constantly adjust the gate valve to keep the level in the same place. You check out how the skimmer is piped up here:

Can anyone help me with this problem?

The vid wouldn't work for me?
Anyways, a couple things could be happening. Your water could be "flushing" out your drain. So the water level will rise, rise, then flush, and drop, then repeat. Also, if the area from which your supply pump draws water has a fluctuating water level, this will in turn affect the water level in the skimmer somewhat, IME.
