Loved them. We had a rather complicated leak in a water filtration system that is set up in a crawlspace area under my main floor. I had my general contractor, his plumber, and one other plumber look at this problem, all of them had recommended different fixes and the thing continued to have a sneaky intermittant leak that ruined the drywall in the ceiling of my basement. Mr. Stalwart was the first one to suggest putting a safety pan underneath the filters so further leaks would go outside. When I had a problem with the work they did the owner came over immediately to check on it. I appreciated the fast response.
