A water valve cracked today at my house and had to call a plumber. He replaced it with a gas valve (yellow handle). He said he uses gas valves because they are better quality.
What he installed looks like this:
I did a search based on what's written on it and it's tested up to 30 bars and seems it can be used for water also... but I'm still not 100% sure.
Where I live, the water pressure is 3-6 atm in the pipes, depending on how tall the buildings are.
Can this be used for water? Are there any disadvantages for using it for water?
