Worcester Bosch Condensate Sump Assembly 87154069240

The Worcester Bosch 87154069240 is a condensate sump assembly, the collection and trap component that gathers the condensate produced as flue gases cool within the appliance and passes it to the discharge pipe. It is a Worcester Bosch spare manufactured for the Greenstar family of gas boilers. Because carbon dioxide from the combustion process dissolves in the collected water, the condensate is mildly acidic, which is why the sump, trap and discharge pipework are made from plastic.

• Water pooling or dripping around the sump, trap body or the joint to the discharge pipe

• Gurgling, backing up or slow drainage through the condensate route
• Staining or damp patches beneath the appliance where condensate has escaped

• Inspect the sump joint seal while the appliance is open and renew it if it is perished or deformed
