This water heater looks nice and new. We notice the TPR valve extension is missing. If the temp and pressure exceed what the water heater can handle it going to start shooting out the side right at you! It's a small fix but definitely worth it. If the water heater can't handle it I'm sure you can't either.
This is one way we go a step further at Lancaster Property Inspections. We take the temperature of the water to make sure it above 120 degrees to kill microbial things in the water but also not scalding hot. Imagine leaving a little one in the bath while you get a towel and the water increase to over a 160 degrees very quickly. Just another way we think of safety.
Cleaning gutters are no fun. We include simple do it yourself links in our reports to help you not only understand but fix some routine maintenance things on your own. Left unattended, this will eventually cause water to go back under the roof and cause issues. We need to take care of the little things as home owners.
