Useful details.

What is the reference number for this product?
Part number
What is included in this set?
1 Pentair R172323 inline check valve
La taille nominale suffit-elle pour confirmer l’ajustement?
Non. Vérifiez le type de filetage ou de raccord, la portée du joint, les dimensions et la référence de l’équipement. Deux raccords de même taille nominale ne sont pas nécessairement interchangeables.
Comment préparer un remplacement?
Photographiez le montage actuel et notez les dimensions et les références. Vérifiez aussi l’état des joints et les adaptations de plomberie nécessaires avant de démonter.
Peut-on intervenir pendant que la pompe fonctionne?
Arrêtez la pompe et empêchez toute remise en marche avant une intervention. Relâchez la pression selon le manuel avant d’ouvrir un élément du circuit.
Comment vérifier l’installation après le remontage?
Suivez la procédure de remise en service du fabricant, puis observez les raccordements et le fonctionnement. Une fuite ou un comportement anormal exige une correction avant l’utilisation normale.
