Leaking Uniseals

[®eefer]

Ahhh I found it leaking again....the uniseals are slightly worn on the insides so I'm thinking I need new ones. I would however not mind going a completly differnt route. Loc, do you have any suggestions of how to create the best leak free seal before I throw my new reactor off the building?

I know this is a crappy pic, but this is what the holes look like. I am trying to get 1/2" pipe going from one chamber to the other with a T in the middle for the pump's intake.

You can eliminate the uniseal by glue a 3/4" coupling that will take your 1/2" pipe.

Glue 1 of these in the hole then put a reducer to 1/2". http://www.marinedepot.com/md_viewItem.asp?idproduct=FT5144

That is just a regular PVC coupling, correct? What kind of glue? Is there a trick to making it look clean? I have Christy's red hot glue that I think will work, but it is hideous looking and bright blue.

Use weldon 16, put a light coat, wait until it drys then put another coat to get a nice bead.

That looks like Larry's or Hawke reactor. It would be just easier to get a new uniseal if you have never worked with weldon/acrylic.

I think you're looking at Loc's reactor, mine is not a full shot.
With my luck so far with uniseals, I don’t trust them at all, especially not in a pressurized application. Technically because of my sump, I could only leak about 5 gallons, but that is 5 gallons too many, not to mention a burned out return pump. Glue sounds much better at this point.

Thanks Loc, I will try it!
