Does exactly what it is supposed to do.

Worked excellent, saved time and money by following excellent instructions provided with gauge purchase.

Gauge works great and it is a must have have for troubleshooting vacuum head potential vacuum leaks. Also, many thanks to George Melton for his patient and invaluable help in troubleshooting the vacuum system issues.

After installation of a Vacuflush system on our Valiant, I thought I had a vacuum leak. The vacuum guage told me quickly that I did not have a vacuum leak, but, instead, my vacuum generator was not pulling enough vacuum. I found I had an unseated o-ring in the bellows/motor assembly. A new o-ring provided a quick fix. Also, George Melton was very helpful over the phone is getting me on the right path.

This product is very useful in maintaining and trouble shooting your vacuflush toilet.

Well built and a necessity for vacuflush tool kit.

Every owner of a Vacuflush toilet should have one of these in their tool box.
