Rated 1 out of 5 by from Top Blows Off within 30 days In my opinion this product does not hold up. I had water shooting up when I was out of town less than month after install. Luckily neighbor saw and shut off my water. I ended up spending more money on a brass product that costs roughly ten times this product. I am out the install money from my handiman. I had a plumber install the other product.
