Description
The Valterra T21301VP Horst Miracle Probes are a four-pack of replacement level sensors for compatible RV black-water tanks. Waste residue and toilet paper can bridge ordinary probes and cause an incorrect tank reading. These longer probes use a Delrin body and a Teflon sleeve to reduce residue-related contact, plus a specially shaped protective roof that helps shield the sensing tip from toilet paper.
Features
- Four replacement probes designed for RV black-water tanks.
- Protective roof helps keep toilet paper and debris away from the sensing tip.
- Insulated probe design reduces unwanted electrical contact caused by residue buildup.
- Fits existing 3/8-inch-diameter sensor openings in compatible tanks.
- Designed to reconnect to existing wiring and compatible probe-style tank monitors.

Before Installation
Confirm your tank uses replaceable, through-wall electrical probes and inspect the mounting holes and existing monitor wiring. The probes are not a complete tank-monitor system. Empty and clean the holding tank before servicing; install and orient the protective roof as instructed for the probe, then confirm that the connections seal securely and the monitor responds correctly.
