Anyone found a good way to stop the water distribution spider tubes from
coming out of the hub in an evaporative cooler? Or am I the only one? I
tried gobs of that rubbery silicon cement and it doesn't work well. I cut
the tubes a bit long so they are bowed a bit when plugged in to keep
tension on the tube, hopfully keeping it inserted in the socket. All
works poorly. Maybe too high a water pump pressure? This season with a
new pump seems a lot worse than usual.

Yes, I knoe, the hub and tubes come with a tube/bottle of cement, but
that is unremovable. If I goof I have to replace everything. A lot of
work on a 100+ AZ day. If a tube gets plugged up - my well water is VERY
hard - the tube is almost impossible to clear. If I can unplug it very
simple. The silicon glue permits that.

Is the usual cooler motor waterproof? I worry when I get a distribution
system leak and water drips on the motor. I suspect I've been lucky
nothing happened.

Your scheme?

TIA

Ken

A bottle of white vinegar in the recirculating pool should help keep the
hard water deposits under control. Silicone makes a good sealer but not a
particularly good adhesive.

I've not dealt with one of these personally, but it sounds like you need
to glue on a thread adapter to the hub and a mate for it to the tube so
you have a threaded connection, not a press fit.

I'm not sure where I'd find such items.
