I installed YoLink water leak sensors around my house and a year after doing so, in the middle of the night, a leak was detected, we were alerted and the water was shut off automatically. Saving a lot of water damage and expensive repairs. This was easy DIY installation and not expensive. A starter kit with the SpeakerHub and 2 sensors is only $50. YoLink smart home products have a long range and long battery life, making them ideal for water leak detection over many years. One of the reasons I installed these was because we have polybutylene pipes which are prone to failing. Same with this manabloc which are very unreliable.
