Pax Bellum ARID Quick Disconnect Question?

[CMO]

I'm setting up a new N24 with quick disconnects and a little stumped as to how I'm supposed to use the quick disconnect on the bottom inlet side without it draining water everywhere upon release. Am I missing something or is the bottom quick connect useless without adding a valve above it which would then require another quick disconnected above that?

It looks like flow rite has the same connectors used on the N24 with what appear as one way check valves? I'm inclined to swap out the bottom quick disconnect with the valved version but want to make sure I'm not missing something first.

Thank you

Lets see if some can help

When you disconnect the bottom connection, a valve inside the quick-connect closes off the water flow. So all is good. Its a nice design.

Went ahead and asked the company directly - see response below. Here is their response in case anyone else runs into the same consideration. Sounds like you may have an older version @Dogtown?

"Hello Chad,

We used to provide a double valved quick disconnect on the bottom and top. We found that they became easily clogged by sand, debri or strands of chaeto. This resulted in the algae crashing from low flow through. It also became more common that people moved to low pressure high flow pumps that couldn't push enough water through the valved fittings.

We had the quick disconnects on your model made for us. They have no bore obstructions to get clogged. We found the valved quick disconnects to be to much trouble for a feature that isn't really necessary. If you run the ARID in a stand simply give yourself enough vinyl tubing length to pull the unit out and raise it higher than the sump to completely drain it by creating a siphon.

If you are running the ARID off a manifold a similar arrangement can be made using a tee fitting and two ball valves.

The quick disconnects are 1/2"mnpt and only teflon taped and siliconed in. They can be taken out with channel locks. If you don't want to damage them use a cushioning material on the jaws of the channel locks.

If you need further assistance I'll be here to answer any questions.

Regards,

Tristan"
