CPR overflow box

[akfirefighter]

Does anyone use a CPR overflow box? I just got one in the mail and am trying to hook it up. How did you connect a hose to the bottom of the box to the fuge? I am having a hard time finding a connector that will work. Any help and pictures of box would be greatly appreciated.

are you talking about the Bulkhead?
the area that connects a line from the overflow bottom to the sump.
heres a pic

I believe the CPR uses a 1 in. bulkhead. if yours didnt come with one you can look at lowes for them. if that is not what you mean i will contenue my search to see if i can help.

My CPR overflow box connected to PVC perfectly. If you are using vinyl tubing, you will need to buy an adaptor for the bulkhead first.

Ya, nevermind this thread I didnt fully read the directions. I went and got a piece of 1 inch PVC it fit in there perfect. I will let you all know later today how it turns out.

Hay,
At least he admitted he didnt read the directions.
I would have tossed em out the window as soon as I opened the box.:mrgreen:

So I got the overflow box installed. Works really well, it is just noisy. the water only stands about 2.5 inches deep in the box so all the run off spashes alot. is there a fix to it?

Get a stronger return pump.

Get a stronger return pump.

I have a 700 gph pump would you say i still need a stronger pump the box is only the 600 one.

 

[Bifferwine]

I don't know... If the noise bothers you, a stronger pump will fill the box up more. But then you also risk having TOO strong of a pump and overflowing the tank. You will have to redirect some of the flow or throttle back if you get a higher rated pump.

Is the front side of those adjustable?
If they are,you can lower the front box a little to take on more water,which will cause the siphon to pick up more,thus dump more in the back box.
I think.

 

[ReefKeeper]

if it is not adjustable ... try building a standpipe for the box.

 

[ReefKeeper]

oh yeah, and i always recommend an aqualifter pump to go along with an overflow box.

 

[fishbait]

I run the pre-filter pad in mine to cut down on the noise.

It is not adjustable, what is the standpipe? Do you have a picture of what one would look like?

 

[Bifferwine]

It's basically a piece of PVC with holes drilled in it. The number of holes you have drilled in it determines how fast the water flows down through the overflow box.

Where do you put the PVC?

 

[Bifferwine]

Over the hole that drains to your sump.

Am I understanding this right? You that PVC drill some holes in it and put it over the cone that drains in the bottom of the box?

 

[Bifferwine]

Yep. I would just replace the cone.
