How to Look

A blog with answers
to your questions about
HOME INSPECTION
and HOME MAINTENANCE

Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

  Although the tank can be mounted vertically or horizontally, we have only seen vertical mounting in our area. A horizontally mounted tank would require additional support.

   Expansion tanks rust as they age, and we look at both the tank and fittings for signs of corrosion. The tank shown at the top of this blog, on closer examination, also has galvanic-type corrosion—a white, powdery buildup caused by an electrolytic reaction between the adjacent galvanized steel and copper piping.


For the statistics on why insurance companies get hot about water heater replacement, read our blog “Why is an older water heater an insurance problem?”

If you are not sure how old your water heater is, find out at our blog “How do I decode the water heater serial number to figure out the age?”

Also, to learn about common installation defects, see our blog “What are the most common problems with water heater replacement?”

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
