Fixing a Cracked Hybrid Water Heater Tray
A cracked condensate tray on your hybrid water heater can cause leaks. Learn repair options and why hand-tightening connections is critical.
Hybrid water heaters are efficient but can have fragile parts. One of the most common issues is a cracked condensate tray. This problem often happens if fittings are overtightened during installation or maintenance.
In this case, the tray cracked when a pipe connected to it was removed. The left side broke loose while the right side stayed in the unit. Attempts to repair with glue and spray sealant slowed the leak but did not stop it completely. Rheem support explained that the tray is a non-replaceable part of the heater. They also warned that only hand-tightening connections is safe.
Question:
Can you permanently repair a cracked condensate tray on a hybrid water heater using sealants or glue?
Answer:
No. Sealants and glues may slow leaks temporarily, but they are not a reliable long-term fix. The condensate tray is not designed for repair. If it cracks, the safest solution is either professional epoxy repair rated for constant water contact or replacement of the unit. Using plumber’s putty, Flex Seal, or glue may buy time, but they usually fail under continuous moisture.
This situation is frustrating because a small plastic tray can impact an expensive heater. If your tray is cracked, limit sealants to temporary use while you plan for replacement. Always hand-tighten fittings on trays and avoid pipe dope or strong adhesives, which make removal harder.
