This is a genuine Davey spare part (ref. 5444REG) for the Regul’Matic salt chlorination control system. It is a threaded reducer fitting designed to house and position a pH or ORP probe at the correct 7 cm immersion depth inside the pool’s return pipework, ensuring accurate water-quality readings.<\/p>\n
The Regul’Matic controller relies on properly seated probes to regulate chlorine production and pH levels in real time. A damaged, cracked, or leaking probe holder must be replaced promptly to maintain a watertight seal and correct probe positioning \u2014 both of which are critical for reliable water chemistry control.<\/p>\n
This probe holder reducer is a Davey Regul’Matic series spare part. It is intended for Regul’Matic pool water-quality controllers that accept threaded probe fittings in the hydraulic circuit. Always cross-reference the Davey part number 5444REG against your unit’s documentation or exploded-view diagram before ordering to confirm fitment with your specific Regul’Matic variant.<\/p>\n
Using an OEM Davey part guarantees the correct thread type, material grade, and insertion depth (7 cm) specified for the Regul’Matic system. An ill-fitting or non-genuine holder can cause probe misalignment, inaccurate sensor readings, or pipe leaks \u2014 potentially leading to over- or under-chlorination of your pool water.<\/p>\n
The reducer fitting threads into a tee or port on the return pipework and accepts the probe body. Ensure the filtration system is off and the line is depressurised before replacing this part. We recommend having a qualified pool technician carry out the installation to ensure a leak-free result and correct probe depth.<\/p>","protected":false},"excerpt":{"rendered":"
