Question of the week 6/28/2015

Here’s how it works:
Must be an interNACHI member to win.

The Awards Committee panel member posts a question in the Education and Training section, once per week at a random time on a random day.

All parts of the question must be answered in one post. You may not post more than once. The first(and only) post counts, get it right the first time.

Do not edit your posts as the Awards Committee can see that time stamp in the edited post…it just makes our sorting it out more cumbersome.

First correct answer (as judged by the question poster, and the award committee) wins. The lucky winner gets one case of “Now that you’ve had a Home Inspection Books” shipped to you. Courtesy of Nick G. Your prize will be shipped to the address on file.

Good luck

To make it easier to clean off the scaling around the waterline.

The pool surface material must be kept wet so it does not crack. The waterline and above is usually tile to protect the surface that is not constantly wet.

The band provides a durable and readily maintainable surface at the water line.

Simplify waterline maintenance.

A ceramic tile band is installed due to aggressive chemical activity at the waterline.

To prevent frost damage.

To prevent frost damage in cold areas.

Because it looks good.:cool:

Human sweat and body oils are harsh and when floating on the surface of a pool, they will attack, wear away, corrode, or otherwise deteriorate porous materials such as concrete or plaster.

All good answers but there is only one first correct!

Nice job, William Forrest.


Thank you.


Finally received my half case of books.
