Test before
you tile.
Waterfall by FlushProof lets you verify every flush reservoir, seal, and connection — without mounting the toilet. Prove the system works before it disappears behind the wall forever.
Three steps to total confidence
From installation to sign-off — without the hassle of mounting a toilet or risking a hidden leak inside a finished wall.
Attach Waterfall
Snap the FlushProof Waterfall adapter onto the flush reservoir outlet. Tool-free, clicks into place in seconds. Compatible with all major in-wall systems.
Flush & Observe
Trigger the flush. Water flows visibly through the transparent Waterfall adapter — confirming flow rate, valve timing, and seal integrity in real time.
Proven. Proceed.
System verified and signed off. Remove the Waterfall, mount the toilet, and tile with complete confidence. Every seal proven before it's hidden forever.
