Reducing the Out-Flow of Eheim 2217 - Kindly guide me

[nagukush]

No, reducing/restricting the flow via a valve won't do any harm to the motor, it will actually draw less power that way.

Even if I restirct the outflow thru the valve thats meant for shutting the pipe while maintainence ? I mean wont it create a back-pressure ? I just want to be sure because the 2217 has been a HUGE investment for me... Kindly guide me...

Here are some thoughts. The flow is going to naturally decrease over time as the media begins to collect matter. Especially true if you use floss at the very top. To fit the spraybar horizontally, mine came with plenty of tubing so you should be able to get it in place somehow. Is the angle pinching off the tube? If so then you might need some extra elbows? As far as extending/modifying the spraybar, the eheim spraybar parts connect by short sections of the return tubing. If you can locate plastic parts of a similar diameter of the original spraybar, you can connect them together the same way and make any shape of custom setup. Maybe ABS or PEX plumbing fittings from your local hardware store?

More thoughts. Simply extending the length of the spraybar should cut down the concentration of flow and make it more reasonable.

You can get real Eheim parts like at bigals, and get another spraybar to extend yours. Plus elbows and etc. lots of stuffs

Here's an old thread from last year too with a pvc custom...

Anything is possible - but i say diffuse the flow and dont try to restrict the filter. Use everything you've got.

I have been using the quick disconnect lever to slow flow for a few years now with no problems.
Eheim actually says it's ok to use the qd's to reduce flow.
I wouldn't set the lever more than halfway tho.

only reduce flow on the output side of a pump, never the input side..

this way there is always enough water to keep the motor cool, if you restrict on the input side, the restricted flow will allow the motor to overheat, and eventually fail.
