Eheim 1250 and intake barb

Nomjr · 04-24-2003, 05:29 PM

My question is that I just bought the pump off someone and it didn't come with an intake fitting. I purchased this one http://65.61.181.4/product.asp?0=207&1=218&3=74

My question is do I need to use some teflon tape on the threads or goop etc?

Use teflon tape, you can find it for under USD $1 at your local hardware store.

If you check out the maximizing flow article on the front page this will make more sense.

:shrug:

What I am describing is a variant of Ph's method modified for the 1250 which 1) removes any flow restriction at the inlet and 2) speeds up bubble removal to an immediate timeframe.
Doesn't have to be at the highest point (in mine it is in fact the lowest) and is easy/low-tech to make.
I will have pictures of the new version within 2 weeks as I work on mad mikees concoction.

This is assuming you have the room of course.

I got spare parts from eheim.com for the inlet, o-ring and locking ring. (~ 10$?) Also got (1"?) nylon threaded bushing at hardware store (almost perfect fit, just needed some sanding on the inside for a slide fit). Then I found a small tuperware (2-3" diam, NOT THE CLEAR STUFF, Translucent (polypropylene)) and after cutting the right sized hole to screw in the bushing and then the barb you got on the other side (can be straight on or at the side, you are in essence breaking the flow here but it still works fine), (can add another fitting on for a fill tube if you want, suggest at lower point to allow fill/drain as needed, can always bend tube up when not in use), used plumbers goop to glue all that together. Then slid the bushing over the spare inlet (PUT LOCKING RING ON FIRST!!!) and gooped that together. Then added another layer of goop over every inside joint again after leak testing and finding you need MORE GOOP!!

While waiting for everything to cure, go find local aquarium store and get some of the coarse filter material (1 box of the blue stuff should last a LONG time) and cut a piece big enough to shove in the tupperware to keep any whirlpools from forming.

When this concoction (yes this is a reservoir) passes leak testing, take the pump / inlet reservoir and fill w/ fill tube, then plug and get the fill tube out of the way.

My original version had multiple inlets to the res from CPU / GPU / NB so looked sort of nightmarish but worked like a charm.

If there is no way to get this to fit, then of course the rule of thumb is if it has threads, tape it alot!.
