    I thought I was brilliant in my new tank set up.  I have drilled the 2 returns in order to eliminate the need for Power heads.  The returns are about 6 inch's from where the water surface is going to be.

    The Big Problem is I have no means to break suction when the power is off.  Is there a plumbing fitting that is like a one way valve? or do I need to start planing some big overhaul before I even get water into it.

    No help here J as I've never dealt with a drilled tank. This is a bump though!

    Get a ball check valve (one without metal) like this:

    From US Plastic.


    My 30 was drilled out with the return coming right through the bottom to about 3/4 up the tank, so I needed to use one.

    Used it for over 3 years without problems, worked great.
    If I had it today, I'd probably clean it once or twice a year, but I never did.

    Would this reduce the GPH?

    Probably a bit.. there is a ball inside the thing that the water goes around, but I didn't notice a big dropoff. Sealed well when the pump was off.

    I've heard that the slime build up makes the seal fail and that the ball can create a lot of racket?
    I have been strongly advised by others not to go with a check valve. But it would be the nices option.

    Well, like I said, I had mine going 3 years, without fail.
    Dosed kalk, never cleaned it.
    I recall it would shoot out some build up sometimes when you started the pump again.
    Don't recall any racket.
    I imagine some are cheaper quality than others. I'd get the best you can.

    People tend to repeat stuff they here, this was my EXPERIENCE. ;)

    Ya I think it may have to do with Quality of the check Valve. I think there are 2 types. 1 uses a flap while the other uses a ball. This could be the difference.
    I will look for the ball type, because I would rather go with a check than create some "T"ed off syphon break.

    Thanks Matt I will try it.

    The other way you might be able to solve the problem ( power outage ) is the put a solenoid(s) in line with the pipe.

    The type to get is a ' normally closed " solenoid that needs power applied to let the water flow through, once the power cuts off the solenoid closes and stops the water flow.
