VERIWIS ATBK01 Adjustable Bypass Sensor Valve Kit, 304 Stainless Steel
Product description
Homeowners replacing a plastic bypass valve in a tank-type hot water recirculation system can use the VERIWIS ATBK01 to add adjustable temperature control. Made from 304 stainless steel, it is designed as a replacement for plastic bridge valve 595926 and works with compatible recirculating pumps, including models 500800 and 500805.
Set the activation temperature from 79°F to 122°F to suit your system’s needs. The kit also supplies connection hardware for installation.
Usage tips
Install the bypass sensor valve at the faucet farthest from the water heater, as directed for efficient whole-home recirculation. When the water is cool, the valve opens to route it back toward the heater, once the selected temperature is reached, it closes. This automatic action supports hot water recirculation without a dedicated return line or an electrical connection at the valve.
For a practical replacement project, the included supply lines, adapters, mounting brackets, and Teflon tape provide the listed installation components in one kit. The valve is intended for tank-type water heaters and use with a hot water recirculating pump. Confirm that your pump setup matches the listed application before installation, and follow the included manual for fitting and adjustment.
What you’ll notice day to day
The adjustable setting is the main difference from a fixed-temperature bypass valve: it lets you choose an activation point within the 79°F to 122°F range rather than relying on a single preset. That control is useful when replacing a fixed or plastic valve and tailoring the recirculation behavior to your household’s preferred setting.
The sensor responds to water temperature automatically, opening for cooler water and closing when the set temperature is reached. This helps manage the return flow through the recirculating system without requiring a separate electrical connection to operate the valve. Its stainless-steel construction also offers a metal replacement option for a plastic bridge valve.
The removable sensor and built-in filter screen make routine cleaning more straightforward: the sensor can be removed for access, and the screen is intended to help catch debris that could obstruct flow. The valve is described as operating quietly, making it suitable for a system installed around everyday household fixtures.
