I like the serviceable one looks nice lol

Oops didn't see they both were I'd do the first one personally

Only drawback to the George Fisher wye one ( besides price ) is the angle you install it on. Some say it works on any angle. Hmm ....

The flapper-style one is called a swing valve. That's what you have now, minus the clear housing, and the unions.
It works best when it's installed vertically, but again, others say it works in other angles. Again, hmmmm ....

Actually, the second, more expensive one, is apparently the more reliable and easier to service one

It does look very easy to service, but IMO the swing valves are tried and true from what I've seen, but then I am limited to what I've seen being wet behind the ears still :lol:

Nothing wrong with the swing valve ..
The wye valve works on weight instead of a spring. It'll never get soft due to wear.
Something to think about, hmm ?

Oh ya, I'm still more wet behind the ears than you are :wink:

Hey, did you check out my build thread ?

I've been using the flapper style one for several years on my system without issue...... that being said, my sump also has enough room in case the seal on the check valve fails.....I bought two when I first plumbed the tank and swap them out periodically to clean them

I am definately going to buy one for my Chaeto tank. Unfortunately it will be the non-clear kind.
I would love to test the clear ones, especially the union kind, but I can only find the best prices from BRS and the shipping is what's keeping me from trying one

Guess I should compile a BRS shipment :rolleyes:
