Check Valves
 

I dont know where should I place this thread, but I am looking for a place in Calgary (if there is any ???) where I can get some check valves like
True Union Swing Check Valve - 1/2 inch Slip x 1/2 inch Slip ( or 3/4, 1" even larger...)

Last time I went to LA for a wedding and so bought some there, but didnt think about needing some more now for another new setup.

Thanks in advance.

The last time I bought a check valve I bought it from Ocean Aquatics (mail-order, one of our sponsors).

Basically, I'd be a little surprised if you'll find anywhere local that has true "tru-union" style anythings (yay for Calgary), but you should be able to find slip valves, either slip or threaded, at either Western Pump, maybe Plumbateria, or Rona and/or Home Depot, depending on how good your local Rona/HD is (some are better than others, I work close to the Macleod Tr/Southland Dr Rona and they have a suprisingly generally decent selection of plumbing bits - but some of these big box stores have a surprisingly hopeless selection - so it's a bit hit and miss depending on what store you go to).

But generally speaking a lot of the more specialty parts we like in this hobby are really hard to find locally. Just try looking for a PVC gate valve, for example.

Oh, hmmm, another idea to try is UFA.

Happy hunting :)

Golds has the check valves in stock but not the true unions.

Thanks guys for your infos.
This made me remeber when I started garthering parts to setup my system, I had to register and order from MD and JL. I guess, I'll have to stick with those "long-distance friends" as it sad but true that :lol: "...(yay for calgary)..." :lol:

Thanks guys.

Red Coral might have some plumbing parts in stock... Maybe give them a call before placing your order online

Not a big fan of Check Valves. IMO its just a matter of time before they fail.

How are you using these check valves? Are you relying on them to stop backflow from your tank should the power go out?
You can design your system without check valves and have one less thing to worry about. ;)

I agree :)

Very nice thinking ! Yes and sad that My tank was designed as such in the first place when I didn't know ANYTHING about SW or reef or anything about this "corrosive hobby"... So, HAVE TO use check valve, but then I found it WILL BE CLOGGED by times, so, the one that can be part out for cleaning is the best, and that where was introduced to the Tru Union friends. With this guy, you can easily part out and clean as often as you like. So, what I did was using a GV in front of CV. Eveytime I need to do cleaning for CV, just shut the GV off and uncrew the CV for cleaning then put it back nice and cleaned. That's why I like those tru-unions.

Any of you have done the same? - Hope none... :lol:

Why where does your return enter the tank?

i got 1.5 true unoins if you want them got 2 extras. I got two on my tank. cant see them failing for many years. Its like saying "dont buy that power head as it will eventually fail...."
