I tried testing the t&p valve on my water heater, and after it kept leaked very badly, I had to shut off the water supply.
I am trying to find a replacement valve, but I don't know how to decipher this.
I'm not sure if this one will work - https://www.homedepot.ca/en/home/p.34-inch-t-p-relief-valve-extended-shank.1000123781.html
I'm in Mississauga, Ontario, Canada, and trying to find something locally asap. Thanks.
