Will it fit my tank?
Made for the second-generation (G2) REEFER S-1000 sump only. G1 and G2 Reefer downpipes are not generally interchangeable, so confirm your tank is the G2 version before ordering.
Compatibility, spares and supersession
Sold as the downpipe only; the gate valve, elbow and bubble trap sponge are separate parts. We could not confirm whether it is shared with the REEFER S-850 G2, so check against your existing part if unsure.
Common questions
Does this fit the original REEFER S-1000 (G1)?
No — G1 and G2 downpipes are different parts and are not generally interchangeable.
Does it include the gate valve or elbow?
No, this is the downpipe only; those are separate spare parts.
