Fantastic Product and Build Quality!

Unfortunately, our house had water damage from a hung clogged toilet than overflowed for less than 30mins. After dealing with this incident I decided it was time to research to figure out what options were on the market to prevent this from happening again. Thankfully I landed on Hawkeye Water Defense. After purchasing a few water blocks for our toilets I decided to also protect our dishwasher, refrigerator, and washing machine. I’ve been impressed with their products build quality, functionality, and price. It’s a no-brainer to install in your home for the extra peace of mind!

We appreciate your kind words and are glad our products provided peace of mind after your water damage experience!
