Derbird Posted September 29, 2014 Share Posted September 29, 2014 Hello folks, I bought a check valve for my 60 cube and have hit a potential problem DOH!. I bought the 3/4" check valve and 3/4" flex hose for the return to the tank. My problem is how to connect the two. The hose simply slips in to the check valve. Since this is going to be a pressurized line I'm not so sure that this will be enough to hold the pressure and not spray water all over my room. Any thoughts on how to reinforce the connection or am I just being paranoid again (crazy) Quote Link to comment Share on other sites More sharing options...
Blackice Posted September 29, 2014 Share Posted September 29, 2014 My guess it 3/4 pvc valve. your going to need to get a barbed pvc fiting glue it to the valve then you can push on the tubing. Quote Link to comment Share on other sites More sharing options...
The ReefBox Posted September 29, 2014 Share Posted September 29, 2014 Or just glue the hose into the checkvalve. Use something like Christy's red hot glue. It seems to work on just about everything pretty good. Quote Link to comment Share on other sites More sharing options...

Also, since yours is transarent, it should be sheilded from light to avoid algae growth. I avoid check valves if I can. Quote Link to comment Share on other sites More sharing options...
pledosophy Posted September 29, 2014 Share Posted September 29, 2014 IME I would just skip it all together. They have never lasted for me and if you plan on them not failing you will have a problem one day, however if you plan on them failing you can avoid that problem, but then you really don't need a check valve anymore. I have tried a few different kinds, never had one last for more then 3 months. Also in the application of your return, I would not want to constrict or depressurize there IMO.

matty Posted September 29, 2014 Share Posted September 29, 2014 If the issue is your return draining to much when power is lost, add some lockline to it so the nozzle is higher in the tank. I decided against a check valve on my old tank after all of the horror stories I read. If you do decide to use it, do like BlackIce suggested.

pledosophy Posted September 29, 2014 Share Posted September 29, 2014 If it is draining to much you can always use a siphon hole, or two if you are paranoid like me as well. I went with the siphon breaks for my systems and have not had a problem with it in 10+ years Quote Link to comment Share on other sites More sharing options...
Jeramy Posted September 29, 2014 Share Posted September 29, 2014 You could always put some nipples on it then calm the hose to the nipples =) Quote Link to comment Share on other sites More sharing options...
