V8043G1018 vs V8043E1012 - what's the difference?

Hi i am new to the forum but i have been reading it from past few weeks. NJ Troppers postings have helped me alot troubleahooting my boiler's problem. End switch on one of the zone valve v8043g1018 is faulty. So i am looking for replacement here in Canada. Local plumbing supply store charges $102.00 for v8043g1018 but i was looking at supplyhouse.com they have V8043E1012 for $59. I want to know what is the difference between the two. Can i buy cheaper V8043E1012 imstead to replace the powerhead on my v8043g1018? Thanks for your help!

The 2010 Honeywell catalog I have does not list a "G" model at all, but I did find some specs on their site...

Honestly, I don't see where there is a difference...

https://customer.honeywell.com/en-US...uct.Rank&asc=1

Check it out ... see if you see any difference?

Other than the fact that yours is a 1" pipe size and the other is the 3/4" pipe size, I don't believe that makes a difference to the power head.

OK, the "G" model has CSA approval, while the "E" model has UL approval.

Maybe the G model is only sold in Canada?

You only want to replace the power head, right? not the whole valve?

40003916-026 - Honeywell 40003916-026 - Replacement Head for V8043E Zone Valves

One thing to watch out for, if you have the 'old style' valves, you can not change the head without draining the system, or otherwise isolating the end valve from the system.

Old style has FOUR SCREWS holding the head to the valve body.

New style has TWO SCREWS and two 'locating pins'.

Hey thanks for reply. The link you have above for g model is for V8043G1026. The one i am talking about is V8043G1018. https://www.amresupply.com/part/V804...LVE-N-C-SWITCH according to the link i have it says its 3/4".


Also it is the new one with 2 screws so easy to change powerhead.

Honeywell musta got confused with me skippin' all over their site... or maybe I did!

I fixed the link in the post above, yeah, it looks like the only difference I can see is the agency approvals...
