⚫ Push-fit gasket pack: the RDWC circuit's consumable
The EPDM gaskets of Growrilla push-fit fittings are the part that guarantees the seal between the bucket and the pipework. In use, they face several stresses: flow pressure, prolonged contact with nutrients, repeated disassembly during cleanings. Over time (generally 12 to 24 months depending on usage intensity), they lose elasticity and may start to weep.
Replacement is very simple: remove the fitting, pull out the worn gasket with a thin screwdriver, slide in the new gasket lightly lubricated with water, and reassemble. The operation takes under a minute per fitting. Keeping a pack of 10 on hand avoids any grow interruption in case of an unexpected leak.
📊 Technical specifications

🔔 When to replace a gasket
Three warning signs:
- Visible weeping around a fitting, even very slight.
- Pressure loss in one branch of the circuit (one bucket receives less flow than the others).
- Planned disassembly: bucket change, adding an extension, seasonal cleaning.
When in doubt, replace preventively: a gasket costs a few cents at pack price, while a poorly managed leak can damage the grow box floor. The pack of 10 easily covers the annual needs of a standard kit (up to 8 buckets, i.e. 16 to 20 fittings in total).
💡 Pro tips: preventive maintenance routine
Schedule gasket replacement at the start of a grow cycle, when the system is empty and easy to handle. Inspect the whole circuit: take the opportunity to rinse the buckets with diluted peroxide, check the air stones and clean the water pump. You restart with a like-new system for 4 to 6 months of production.
Store new gaskets away from light and heat, in their original bag, to preserve elasticity. Storage life: several years without degradation.
