We had the Patriot people come to our house in Oct. 2012 to fix a problem with a leak (Sunday evening). They came quickly and were so professional we were surprised. They fixed the issue quickly.
In March, we thought we had an issue with what they fixed and called them. They again came by quickly and determined the issue was due was not due to a leak but how folks were using the toilet. :-)
We were very appreciative for the quick response and how courteous, professional and friendly they are.
