A O Smith 100111630 Pressure Switch

Description

Purchased new in May from Amazon (https://www.amazon.com/gp/product/B086MMQL3S/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1) to have on hand as I was getting an intermittent failure that AO Smith tech support diagnosed as a failing pressure switch.  It i
ncludes switch, hose, instructions and bag it came in, as pictured.
Other pictures are of my water heater and vent system, which I e
nded up replacing entirely due to a leak in the tank and never used this part.  The amazon return window expired so seeing if someone else can use it and save a few bucks.
Make sure you know this is the part you need for your water heater.  I called AO Smith and was provided this part number (100111630) but cannot tell you if it will work for you.
