Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the B&K ProLine 1/2 in. MIP MHT Anti-Siphon Chrome Sillcock — a rugged outdoor faucet built for reliability, safety, and a polished, weather-ready look. With frost-proof design, anti-siphon protection, and a durable chrome finish, this sillcock is designed to perform season after season in demanding outdoor environments.

The ProLine sillcock is engineered to guard your potable water from backflow while standing up to cold climates. Its frost-proof construction places the active valve deeper inside the wall, helping your outdoor faucet stay operable when temperatures dip, so you can water your landscape with confidence all year long.

Why this model stands out:

  • Anti-siphon protection keeps backflow out of your supply line, helping you meet safety codes and protect your home's drinking water.
  • Frost-proof design minimizes the risk of frozen pipes and burst fittings by isolating the valve from the exterior environment.
  • 1/2 in. MIP inlet to MHT outlet offers straightforward connection to standard supply lines and readily accepts garden hoses for effortless outdoor water use.
  • 8-inch length provides ample mounting depth for secure installation on exterior walls and through-wall configurations.
  • Multiturn handle enables precise, easy control of water flow, even with gloves on during winter or early-morning tasks.
  • Lead-free construction aligns with modern safety standards, ensuring a cleaner, safer outdoor water experience.
  • High-pressure tolerance rated up to 250 psi supports typical residential irrigation, filling, and outdoor chores without compromise.

Ideal for homeowners in regions with cold winters, property managers maintaining rental properties, and landscapers needing durable, reliable exterior faucets. If you want an exterior faucet that combines safety, durability, and a clean chrome look, this ProLine sillcock delivers.

Practical use cases:

  • Attach standard garden hoses to the MHT outlet for lawn irrigation, filling buckets, or washing outdoor spaces.
  • Pair with an interior shut-off and winterization plan to drain residual water, reducing the risk of ice damage during freezing conditions.
  • Regularly inspect the anti-siphon vent to ensure optimal backflow prevention and long-lasting performance.
