Q: What features help identify the faucet?
A: Key traits to note:
- Does it have a vacuum breaker or anti-siphon on top behind the handle?
- What is the length (thru-wall dimension) — 6 in, 8 in, etc.
- The shape and markings on the stem (threads, square or round, number of threads).
- The handle style (wheel, star, or lever). Some brands use unique handle designs.
- Any logo or cast letters in the body (often “BK”, “M”, or brand name) as per the BK Products identification guide. :contentReference[oaicite:1]{index=1}
Q: Are there common brands with 6 in frost-free models?
A: Yes, many brands make 6-inch frost-proof faucets. Examples include:
- Arrowhead Brass — their 6 in. lead-free anti-siphon models.
- Plumber’s Choice — 6 in anti-siphon sillcocks. :contentReference[oaicite:3]{index=3}
- ReliaBilt — they sell a 6-inch brass frost-resistant sillcock. :contentReference[oaicite:4]{index=4}
- BK Products — many frost-proof faucets carry a “BK” or “M” triangle marking as part of their identification system. :contentReference[oaicite:5]{index=5}
Q: What measurement matters most?
A: The “stem length” or “inside stem measurement” matters a lot. BK’s identification guide shows different part numbers based on that measurement. Having that length tells suppliers which replacement stem fits your unit.
Q: How to find the replacement stem or kit?
A: Once you have brand clues and the stem length, you can:
- Contact the brand with photos and ask for a stem or repair kit matching your spec.
- Search for “6 in frost-free faucet stem kit ” or “6 in sillcock repair kit.”
- Visit plumbing supply houses with the faucet part or measurements to match by eye.
Q: What to do now to proceed?
A: Steps to take now:
- Remove the handle and bonnet nut to expose the stem.
- Measure the stem length (tip to tip), count threads, and note thread type.
- Note any cast or stamped brand markings on the body (BK, M, arrow, etc.).
- Take clear photos and send them to specialty plumbing parts vendors or the faucet manufacturer.
