Cascade electric 40 gal. water heater age please.
TPR missing verbiage is this sufficient? The TPR valve is missing. This is a safety concern. Suggest installing required temperature pressure relief valve as a safety measure prior to closing.
Thanks
Most likely made by GSW in Ontario (now owned by A O Smith of the US). If so, year would be 02/month- January
My guess would be 2001 or 2002.
· Safety Issue:** For safety reasons, we recommend that you have a temperature and pressure relief (TPR) valve installed on the water heater immediately.* The lack of such a valve is a safety concern.***
Nice graphic Marcel.
Scott, personally I don’t like the word “concern” in this and other hazardous situations. I would choose a ‘stronger’ word to help with the client understanding the seriousness of the problem.
Realtor translation:
Concern… I am concerned that you may get an ow-ey if you don’t install a TPRV in the future.
Hazard… You will blow up and die if you don’t install a TPRV immediately.
Just sayin’. 
Good one Jeff nice analogy! I will change it to reflect that. I have already spoke to the client and warned him during the inspection. I asked him to google water heater blow up on youtube…it is very enlightening. Thanks for the help Marcel!!!
Thanks Guys!!

Send your clients to these sites after explaining what can happen when the TPR and the thermostat malfunction.
I could not find it but another TV show called “breaking point” exploded a 40 gal WH inside a 900 sq ft post war II house. The House was totally demolished. Because the WH was inside confining the energy caused a lot more damage then the open side in the myth busters video
Thanks Vern for the info, I did send a link to the customer from Mythbusters yesterday. I have also placed an informative picture of the TPR and two links on my site as to what can happen on pressure buildup.
