Red Sea Reefer 170/170A/XL200 Aquarium Sump Overflow Downpipe
The confirmed factory downpipe for a REEFER 170 or 170A sump. This genuine Red Sea sump overflow downpipe carries water from the display's overflow drain into the sump chamber on the REEFER 170 and 170A – it's listed in Red Sea's own cabinet installation manual for both models, matching Red Sea stock code R42219.
Key features
- Genuine Red Sea part – matches Red Sea's own stock code R42219.
- Confirmed fit – listed in Red Sea's official REEFER 170/170A cabinet installation manual, and in independent Red Sea resellers' parts catalogues for the XL 200 too.
- Restores correct sump water level and noise control – a cracked or missing downpipe lets the overflow run rough and can affect sump water level.

Will it fit my tank?
Confirmed for the REEFER 170 and REEFER 170A – both are listed against this part number in Red Sea's own cabinet manual. The REEFER XL 200 is also listed against stock code R42219 by authorised Red Sea resellers (it shares the same cabinet and sump dimensions as the 170), though we could not find R42219 listed against the XL 200 on Red Sea's own official parts diagram directly. If you own an XL 200, check with us before ordering and we'll confirm against your unit.
Suitable for, and not suitable for
- Suitable for: REEFER 170, 170A and XL 200 owners replacing a cracked, warped or noisy overflow downpipe.
- Not suitable for: REEFER G2 or G3-generation systems, or MAX-series tanks – these use different downpipe parts.
Warranty and delivery
Covered by Red Sea's standard manufacturer warranty against defects, in addition to your rights under the Australian Consumer Law. Ships standard.
Common questions
Will this fit my REEFER XL 200?
Very likely – multiple authorised Red Sea resellers list stock code R42219 as fitting the REEFER 170, 170A and XL 200, and the XL 200 shares the 170's cabinet and sump dimensions. We haven't been able to confirm this exact part against an XL 200 directly on Red Sea's own parts diagram, so message us your tank's model plate details if you'd like it double-checked before you order.
What's the difference between this and the inner downpipe?
This downpipe carries water on into the sump chamber. The inner downpipe (sold separately) sits inside the overflow box itself – they're different parts.
Does this fit the G2-generation REEFER 170?
Not confirmed. Red Sea's G2 parts generally carry their own "G2" stock codes; check with us if your tank is a G2.
How do I know if I need this part?
A noisy or splashing overflow, or visible cracking around the sump downpipe seat, are the usual signs.
