Question about drilled tank/wet dry plumbing

[misterted]

I am going to make a move and buy one larger tank thus selling all my other tanks.

So I have been researching and came across this type of setup:

The tank has this on both sides and I'm not sure how this actually works.
How does the tank water get into the filter and where does the filtered water get back into the tank?

If anyone can explain it would be a great help.


Thanks
Ted

Most tanks that are drilled have at least two holes drilled. One hole is for a standpipe (usually with a strainer attatched) where water is removed from the tank and goes to a wet dry filter. This standpipe can be seen in the picture. Tank with no hood on the right. The standpipe is the narrow white PVC tube. Black strainer is on top. The other pipe is a return pipe. Filtered water is returned from the wet dry through this pipe. Return pipe is the one with the elbow. The water level in the tank will be at the level of the strainer. Usually the return pipe is at the opposite end of the tank from the intake. In the picture, the tank on the left appears to have two intakes and two returns, one on each side. Hope this helps.

What Joe said and , the pipe that takes the water from the tank is gravity fed meaning its not pressurized and mearly overflows from that box down the pipe and drops over the filter media. The return pipes are attached to the pump which is in, or piped to the wet dry itself. It forces the water back to the tank. You'll probably have to purchase the pump , it's rarely included.

OK, thanks. The wet/dry filter I'm looking at has 2 pipes over pads and bioballs that spit the water out but how does the water return to the 2 return pipes? Do I need 2 water pumps in the sump?

And another question, In the event of a power outage I know the water above the strainer will drain into the sump but once power is restored and the pump sends water back to the tank there should be no problem, correct? It should just start the process all over without any care from myself?

One pump and a tee with two valves to adjust the flow how you like it between the two return's

When power returns, you need not do anything. like you said, the process will start on its own.

Thanks everyone.
I appreciate the help.

Just have to make sure your stand pipe's or outlet is high enough to stop draing as not to over flow your sump if not you can end up with a real mess ( trust me I have done it)

i used check valves to prevent overflow during an outage
