Just asking because I'm going to the beach today and I'm legally blind. So dose the water affect the anti reflective coating? And how do I know if i have it?Thanks:)
It's not designed to, but smoke of all kinds contains CO, so it is possible.
No way can you use PVC fittings on a gas line, they are 2 different compounds, and very illegal in the UK.
In most smoke detectors a steady green light means its working properly, a blinking green light means it is either on battery backup or theres a trouble such as a dirty screen. Red means it is in alarm for either no power, low battery or you have a actual fire.
