Ask your QuestionHello, I’m just installing a soaker hose system and don’t know if my existing outdoor tap (fitted in 2014) has a double check/no return valve.
Can anyone advise if it’s likely to have?
Many thanks.

"Most probably yes, but only way you could confirm by removing the tap from the bracket and check."
