A spare sprinkler wrench is required for what?

• A. Every type of sprinkler.
• B. Only for wet type sprinklers.
• C. Only for dry type sprinklers.
• D. Not required; optional.

Answer: (A)

Having a spare sprinkler wrench on hand is essential because different sprinkler types require different tools to service them safely and without damage. In many systems you’ll find a mix of wet, dry, and other head types, and each type has its own interface or nut that you need to turn or hold during inspection, testing, or head replacement. If you only bring a wrench for one type, you won’t be able to service other types on the same job without improvising, which can damage components or delay work. A spare wrench ensures you’re prepared to work with every type that’s installed, keeping maintenance on schedule and protecting the system.

That’s why the best practice is to have a spare wrench for every type of sprinkler that could be present. Options that limit the wrench to just wet or just dry types or that call it optional don’t reflect the reality of mixed systems and the need for versatility in the field.
