The Ideal 175896 Sump & Cover Replacement Kit is a genuine Ideal spare part that replaces the condensate sump and cover assembly on compatible Ideal condensing boilers.
In a condensing boiler, the sump collects the acidic condensate from the heat exchanger and guides it to the condensate trap and drain. A cracked, warped or leaking sump, or perished seals, can cause condensate leaks inside the casing, ignition or flue faults and reduced efficiency. A new genuine sump and cover restores a proper seal and keeps the boiler running safely.
What’s in the Box
- Sump body with pre-fitted rim seal
- Sump cover plate
- Rubber seal / grommet
- 2 × sealing washers
- 2 × fixing screws
Compatibility
- Ideal Logic & Logic+ Combi 24 / 30 / 35 (including ESP1 / ESP variants)
- Ideal Logic System 15 / 18 / 24 / 30 (XN & XO serial prefix onwards)
Please check your boiler’s model and serial number before ordering. Not sure? Call or WhatsApp us on 020 8553 5315 with your boiler’s GC number and we’ll confirm the right part.
