ehiem 1262 hobby pump

I can't get the connectors on my ehiem pump to fit my pipes, they don't seem to be 1" or 3/4", has anybody else used on of these, and if so what did you use for connections?

This is the email I sent that explains in more detail.
I recently ordered a ehiem 1262 hobby pump from you.

Hose Connection (Suction Side): 1"
Hose Connection (Pressure Side): 3/4"

is the descirption on your website for the connections on the pump.

The connectors that came with it though are NOT this size. Only the threaded adapter part that goes into the pump is that size, the side that I would attach hoses or pipe to is not 1" on the suction side and it is not 3/4" on the pressure side, neither is it any standard size.

How am I supposed to use this pump. The drain on my tank is 1" and the return is 3/4", which is why it is important to me that the pump uses those sizes for suction and pressure.

I emailed eheim about this about a week ago with no response yet!

I don't want to return the pump, I just want adaptors that are the right size, but can't find any anywhere.
Any advice or suggestions would be greatly appreciated!

This sounds like a major pita. I thought the hobby pumps fit the 12/16 mm tubing??? Anyways, you could always try hose couplings from Lowes?

I would suggest trying a phone call. Always much better IMHO than an Email. I know it's an archaic means of communication but it almost always gets results.

Second Eheim pumps always use odd size tubing. They also use metric tubing. While the threaded fittings are English sizes the rest of the fittings are made for Eheim tubing.

A simple Google search for "eheim hobby pump" turns up this page which gives you the sizes of tubing needed.

Default Thanks for the suggestions

I actually received an email back from ehiem today
Thank you for your e-mail. As the EHEIM 1262 is manufactured in Germany, the thread connectors and outputs are not in metric system. Also the 3/4" output nozzle is to be used with flexible tubing and not with PVC pipes. I'm sorry for the inconvenient but EHEIM doesn't manufacture any adaptors that will work with 3/4" pipes. In order to connect the output we recommend to use EHEIM hose # 4005943 which is 16mm inside diameter and 22mm outside diameter.

Please do not hesitate to contact me if you require further assistance.

Yours truly,

Of course my problem is if the hoses are metric, how do I hook this thing up to anything else in my loop, I planned on using the eheim as a pump for an ocean clear canister filter, and have the 1" drain from my aquarium go right to the suction side of the pump. May have to just get a different pump.

Default Good news

This is the email I recieved today from the site I bought the pump at, much more promising response than I got from eheim. I'm crossing my fingers.

Thank you for contacting us

The actual threaded port for the outlet is 3/4", but it's not a standard US
thread-I called eheim, and they're sending me a link to where the proper
fitting can be obtained-evidently this isn't the first time they've received
this feedback (we place the information we're given by eheim on/ for our
site).As soon as I get it from eheim I'll send it to you.

Please feel free to contact us with any future questions/comments.

Sincerely Yours,

Alan Lavitsky
