GHL Maxi - RO tubing mod

[AZMSGT]

I had my Maxi up and running with RO tubing as the in and out tubing. However I had one line pop off on me and I have not trusted the set up.

I saw a few pictures where APEX owners modified their DOS. Since the pump heads are practically identical I thought I would modify my MAXI pumps.

You need to cut the end off or it will get in the way of the tubing when the RO tube is installed in the new fittings.

You need to use a sealant on the threads before installing the fittings.

These are the fittings I installed. I only tightened them by hand. Using a wrench or anything else I was worried about breaking something. Got them on Amazon

I installed locking clips to ensure no slipping of the RO lines.

Here’s the finished pumps.

So far so good, just finished it about 3 hours ago. Ran 1000ml through each pump for leak checks.

It will be 100%, the fittings don't leak unless they're physically damaged.

Thanks for sharing!

JG fittings out of the factory would be great - they are pretty common if not the industry standard in reefing.

Nice thing is it’s an easy mod.

That is brilliant, using the put locks. I am using silicone tubing instead of the water line tubing. The silicone is seating better without have to over stress the connections to the head.

I am print out the P-touch labels now.
