Abstract
A toilet refill restrictor apparatus includes an adapter interposed between a fill valve and a refill hose. The adapter is non-removably coupled to the fill valve and is configured with a larger proximal pathway, and a smaller distal metering pathway for restricting the refill flow rate. The adapter may be coupled to a shortened horizontal outlet formed at a top portion of the fill valve. The horizontal outlet is shortened to a length such that the refill hose cannot be connected directly to the outlet. The adapter may also be coupled to a fill valve without a horizontal outlet where an exit port is defined in the vertical conduit of the fill valve. The adapter includes a securing mechanism to prevent removal from the fill valve without excessive force or breaking the adapter.
