I wouldn't suggest anything smaller than 3/4" but if you want to try 1/2" make 2 and use one in each corner. 1/2" would be very easy to clog and then you'd have water everywhere. Having 2 will give you a little insurance.

Last ones,, I found some 1/2 (16mm) elbows in my stock pile, just need to buy the piping and a T so i tried it out. It didn;t keep up. i used a 2200L/hour and i had to adjust the intake on the pump to almost closed, like 85%. So thats not gonna cut it. .. Im gonna for for the full inch,

My question is. Does the depth matter much, considering it skims the surface anyhow,

Will a longer (deeper) system be able to create more sucction or does the length matter not.

As long as everthing is uniform, as per the design, does it have to go deep or can it be nearly all elbow and very little piping

I also have a quick question, do you attach the check valve by pvc cement or silicone?

 

[CHOMPERS]

You will need to change the check valve periodically, so you need to use silicone. Match the mounting hole to the size of the check valve's end. It should be a snug fit when you dry fit it. When you silicone it, just put it around the end of the check valve, making sure you don't plug the end. Then install the check valve and let the silicone cure.

... It didn't keep up...

... Does the depth matter much..

1. Use the pipe sizing thread in the sticky section of this forum.

2. It needs to be as long as possible. The length is also in the same sticky.

Thanks CHOMPERS... I did a trial run on my tank before i glued the Pipe fittings in place and boy does she work well! Even with the minor leak in the bottom u outside the tank, it flowed like a champ! Very pleased with this design and i did a 20 min power failure and it kept primed with no problems!

I know this may have been mentioned before, but if you ge a lot of noise from the air intake tube, I found that if you put a piece of airline tubing down to the "T" on the intake it really helps a lot on that sucking noise.

Just to clarify, the airline should extend below the T.
