Eheim Pump Plumbing
 

I'm sure a lot of you are running Eheim pumps and I was wondering how you married the barbed fitting on the pump to your PVC plumbing? Descriptions with pictures would be helpful. Thanks!

Tagging along

I haven't plumbed mine yet, but my plan was to use close nipples with lots of thread sealant, and then reducing females to my true union ball valve on the sump side and a regular union on the output side.
I'll tag along too to see what others use.

That barbed fitting should fit into 1" spa-flex PVC.

The factory sizes for the 1260 and 1262 are 1" input and 3/4" output.
Those dimensions are for I.D. hose.
Spaflex and such are measured by the O.D. of the rigid PVC used, so not a good match.

Hmm, maybe my 1262 came with a different adapter, because it fits perfectly into the 1" spa-flex I use.

Easy, use a section of vinyl hose from the barb on the pump to a Spigot-Slip adapter like these:

The vinyl hose is a good idea anyway as it helps to isolate the pump's vibrations from the rest of the plumbing.

Now you're makin' me want to go look at all the fittings that came with my 1262 ...

Agreed, but it's nicer to use spaflex as there is no need for hose clamps

1262
 

For 1262's you can use a 3/4 male to female PVC piece . I then use a link of 3/4 spa flex to get rid of any vibration despite there being pretty much none.

thanks for all the feedback. I just ordered a bunch of 3/4" and 1" spa-flex so hopefully it should be here this afternoon and I can continue with the plumbing. :biggrin:

Nate, the slip - threaded reducer you are talking about bottoms out in the pump well before it starts to tighten up. The short nipple I linked does tighten some so I feel would be a better seal.

Use
 

Use Teflon tape or cut off some threads works just fine on my last 5 installs of 1262's

Where did you order the spa-flex from?

So I received my spa-flex today. I order 3/4" and 1". The 3/4" is for my return and the 1" is for my overflow plumbing. As it turns out the 1" spa flex fits onto the barbed fitting quite well. I'll have to heat up the spa-flex before I put it over the barbed fitting on the pump. it's quite tight and I don't want to break the fitting on the pump but it's looking like it will fit quite nice.

For the person that asked where I ordered the spa-flex from, I ordered it from Western Pump. The pipe was cheaper than I thought. The price of a 10' section was about the same as a 10' rigid piece of pvc purchased from Rona. Shipping in town was only $20 so that was a no brainer as well.

For such pumps I've always used rigid PVC pipe, whatever size is just slightly smaller than the barb diameter. Just heat up the pvc pipe with heat gun or whatever you have and force it around the barb, let it cool and you've got a solid connection but for internal sump use only.
