VACUUM BREAKER (58BFP) FINE TH

The VACUUM BREAKER (58BFP) FINE TH is a:

🚰 58BFP Vacuum Breaker (Fine Thread Type)

It’s a backflow prevention device used on hose bibs, faucets, or plumbing fixtures to prevent contaminated water from being siphoned back into the potable water supply.

⚙️ Breaking down the description

• VACUUM BREAKER → anti-siphon safety device
• 58BFP → model/series identifier (commonly associated with Watts-style or compatible vacuum breaker assemblies)
• FINE TH → fine thread connection (as opposed to coarse hose thread)

🔧 What it does

A vacuum breaker:

• Prevents back-siphonage (reverse flow of dirty water)
• Protects drinking water systems from contamination
• Allows air into the line when pressure drops, breaking the vacuum

🏠 Where it’s used

Common installations include:

• Outdoor hose bibs (spigots)
• Irrigation systems
• Utility sinks
• Mop sinks
• Commercial washdown stations
• Some appliance water connections

🧰 Key features

• Brass or corrosion-resistant body
• Spring-loaded internal check mechanism
• Air inlet that opens under negative pressure
• Threaded connection (fine thread in this case)
• Often required by plumbing code in outdoor applications

🧠 Simple explanation

It’s basically a safety cap for a faucet that stops dirty water from getting sucked back into your clean water supply if pressure drops.

⚠️ Important note

• “Fine thread” must match the fixture exactly (hose thread mismatch is very common)
• Not all vacuum breakers are interchangeable (hose bib vs irrigation vs fixture-specific designs)
• Some are tamper-resistant or non-removable by code
