If you're not sure which you own, check your purchase documentation or the model details on your cabinet, or contact us with a photo of the overflow box and we'll help confirm before you order.\u003c\/p\u003e\n\u003ch4\u003eWhat causes a Reefer overflow to go noisy?\u003c\/h4\u003e\n\u003cp\u003eUsually a downpipe that's cracked, warped, blocked, or sitting slightly proud of its seated position, which lets air into the siphon. Replacing the outer downpipe with the genuine part restores the original clearance the silent-overflow design relies on.\u003c\/p\u003e\n\u003ch4\u003eCan I use a generic pipe instead?\u003c\/h4\u003e\n\u003cp\u003eGeneric pipe rarely matches the Reefer's exact internal and external diameters, and even a small mismatch breaks the Herbie-style siphon that keeps the overflow quiet. The genuine part is the reliable fix.\u003c\/p\u003e\n\u003ch4\u003eIs fitting straightforward?\u003c\/h4\u003e\n\u003cp\u003eYes — it's a direct swap for the existing outer downpipe, no cutting or solvent welding required.
