I don't know if your area enforces the requirements on these BFPs like my city, but I am required to have a certified inspector perform an annual test and re-certify my BFP is working. If it has a leak or is not holding, the inspector has the necessary O rings, seals, etc. to make the repair. It seem a bit unusual that a 1 year old device would be leaking, but stuff happens. This testing requires a license and test equipment and is not a DIY job. If I do not get the certification done, the city shuts my water off. Seems to me that the last time I had to have repairs made, it cost about $30 above the $35 testing fee. I do not have a Watts, but it appears to be similar.
