{"product_id":"flood-drain-fitting-13mm-19mm-hydroponic","title":"Flood \u0026 Drain Fitting (Full Set) | 13mm \u0026 19mm Hydroponic Tub Outlet System","description":"\u003cp\u003eEbb and flow is one of the most reliable and widely used hydroponic methods for a reason. Timed flood cycles saturate the root zone with nutrient solution, then drain completely, allowing roots to breathe between feeds. The quality of your flood and drain fittings determines how well that cycle works. A poorly sealed outlet fitting means leaks, inconsistent water levels, and unpredictable drain cycles. This full flood and drain fitting set is built to eliminate those variables.\u003c\/p\u003e\n\u003cp\u003eAvailable in 13mm and 19mm outlet configurations, these fittings provide controlled water inlet, drainage, and overflow management for grow trays, flood tables, and hydroponic reservoirs. The full set includes everything needed for a watertight installation, with threaded bulkhead fittings, seals, and barbed outlets that connect directly to standard hydroponic tubing. Whether you're setting up a new ebb and flow system or replacing worn fittings on an existing one, this set gives you a reliable, leak-resistant foundation for consistent flood and drain cycles.\u003c\/p\u003e\n\u003ch2\u003eHow It Works\u003c\/h2\u003e\n\u003cp\u003eDuring the flood cycle, nutrient solution is pumped into the grow tray and rises to a controlled height set by the outlet fitting height. When the pump stops, gravity pulls the solution back through the drain fitting and into the reservoir below; pulling oxygen down through the grow medium and leaving the root zone flushed and oxygenated ready for the next cycle. The overflow fitting acts as a failsafe, maintaining a maximum water level limit to prevent overfilling regardless of pump timing. Together, the inlet, drain, and overflow fittings give you complete control over every phase of the flood and drain cycle.\u003c\/p\u003e\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull set for complete ebb and flow installation.\u003c\/strong\u003e Includes inlet, drain, and overflow components with seals and washers for a watertight fit straight out of the pack.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise flood level control.\u003c\/strong\u003e Outlet fitting height determines the maximum water level in your grow tray, giving you repeatable, consistent flood cycles every time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverflow protection built in.\u003c\/strong\u003e Prevents overfilling and system instability if pump timers run long or fail to shut off on schedule.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeak-resistant bulkhead fitting design.\u003c\/strong\u003e Threaded bulkhead with rubber seals creates a watertight seal through the tray wall, eliminating the drips and slow leaks that undermine system reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable high-strength polymer construction.\u003c\/strong\u003e Built for long-term use in nutrient-rich hydroponic environments across multiple grow cycles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEbb and flow hydroponic grow trays and flood tables\u003c\/li\u003e\n\u003cli\u003eHydroponic reservoir and tank outlet fittings\u003c\/li\u003e\n\u003cli\u003eIndoor grow room recirculating nutrient systems\u003c\/li\u003e\n\u003cli\u003eCommercial hydroponic production setups\u003c\/li\u003e\n\u003cli\u003eGreenhouse flood and drain irrigation systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes.\u003c\/strong\u003e 13mm \/ 19mm outlet compatibility\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type.\u003c\/strong\u003e Barbed outlet with threaded bulkhead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial.\u003c\/strong\u003e High-strength polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes.\u003c\/strong\u003e Inlet\/outlet bulkhead fitting, drain fitting assembly, seals and washers, threaded connection components, outlet barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction.\u003c\/strong\u003e Water inlet, drainage, overflow control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication.\u003c\/strong\u003e Ebb and flow hydroponic systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironment.\u003c\/strong\u003e Indoor, greenhouse, commercial systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Set Weight.\u003c\/strong\u003e Approx. 0.2 to 0.4 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Bought Together\u003c\/h2\u003e\n\u003cp\u003eThese flood and drain fittings are designed to work as part of a complete ebb and flow system.
