CUSTOMER REVIEWS

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Great product at a great price Had a failure of the 30 year old original valve. Looked high and low for an economical and local solution. Order online and it came earlier than first estimated. The product fit well and is far superior to the original. With preparation, tools, lights, and crawling in and out of the crawl space, I was at the DIY for 90 minutes. Leak check 24 hours later showed a very good seal. April 27, 2015
