Plumbing question
Hi,
Just wondering if anyone has any experience plumbing an Eheim needle wheel pump. I am having some real issues maintaining any sort of decent flow on the return line. I'm not great with plumbing. Please let me know. Thanks.

Re: Plumbing question
Let me rephrase the question.
Suppose I wanted to make (because the commercially available ones are too small in diameter) an intake for a beneath- the- tank water pump.
I would like the intake to hang on the back of the tank, much like the intake of a canister filter, and to be 1" in diameter.
Does anyone know how to fashion one of these? What would you use for an intake screen?

Re: Plumbing question
That's roughly what I am trying to accomplish, thanks. The foam over the intake would make things a lot easier than trying to fasten a screen in place.
The only other difficulty I could see is to try to incorporate a priming mechanism (the pump is not self priming). I'll see what Joey has to say about that

Re: Plumbing question
2 words. Sprinkler fittings
I made myself an output for my Fluval 304 in litterally 3 minutes.... mind you i spent an hour or so drooling over the various options that I was coming up with as i was piecing pieces together. My son didn't appreciate being stuck in teh shopping cart for the whole time.... or maybe that was the time he fell asleep in the shopping cart. 
they are usually black or grey, and as long as you have the right diameter, they are almost always interchangeable... some differences in threads may come up. you also have risers that are prethreaded. and the best thing is that if you tighten them right, they are practically self sealing.
pieces vary but usually they are extremely reasonable ($0.50 to $4.00 depending on the piece
here are the pics of the first one i put together...

Re: Plumbing question
Thanks Chad.
Today, I was just informed me of the existence of these:
These should make life easier. They are available from MOPS in a variety of sizes.

"Threaded Suction Strainer"
Cool find.

hey if the threads match up, depending on colour preferences, the sprinkler fittings would compliment this quite well.
