Do I need a stop/check valve?

[mugsy]

Hi all, i have fire ext and regulator and will be using inline diffuser.
Is it a good idea to put one of those stop valve things on the tube to prevent water flowing back to regulator??
Thanks

Hi I fitted one just in case, it’s a CO2 art one, but I think the regulator actually has a valve within that stops water getting back through.

Unless you know the reg has one for definite, you should fit one. Water moving back through the pipework to the solenoid and/or regulator can cause issues.

I presume you mean a non return valve and would invariably have to say 'yes!'

Always have a non return valve on gas lines going into your tank. Even without considering protecting equipment connected to the line, if the line disconnects from the regulator or air pump the whole tank volume of water can drip onto your carpet through it. A £2 piece of plastic for that level of peace of mind is absolutely worth it imho.
