I also found a pinhole on the top side of the suction/inlet connection. That is definitely a moulding or laminating quality issue. So if you get the water leak from the front cover bottom grating, remove the front cover and connect the pump without it to be able to see where the leak is from.

Seems leakage comes not always from the seals on the shaft. I bought the replacement kit and when I disassembled the pump I found that the pump housing close to the output port has a pinhole leak at a seam of the injection moulding part. Definitly a production or construction issue. Pump is 23 month old, I hope the dealer will handle this properly and newer parts are better because I really like this pump.

Bonjour, sympa cette video mais je ne vois pas la solution à mon problème, à savoir de l'eau qui goutte au niveau de la petite grille en dessous de la pompe. Je ne me vois pas démonter toute la pompe pour ça. Merci d'avance si vous avez une idée de solution? Je suis super content de ma pompe mais j'ai vu que je n'étais pas le seul à avoir un souci à ce niveau là.. Un souci de série?

Bonjour - Merci d'avoir contacté. Je poserai cette question à l'un de nos spécialistes produits. En raison des vacances, le temps de réponse peut être un peu plus lent et je m'en excuse. Bonne année! Bien cordialement, Maria

Salut! Nous avons maintenant eu des nouvelles de nos spécialistes produits. Il peut y avoir deux raisons au problème que vous rencontrez : 1 : La raison typique est la condensation. Cela ne peut pas être éliminé, mais nous vous recommandons de installer la pompe dans un bac d'égouttage ou à proximité d'un siphon de sol. 2: Une autre raison peut être une fuite du joint d'arbre. Le joint d'arbre fuira pendant le période de rodage, mais cela devrait s'arrêter après trois heures de fonctionnement continu ou après opération pendant une semaine. Normalement, la fuite du joint d'arbre sera si faible que l'eau va s'évaporer. Si la fuite est supérieure à une goutte par minute, il y a un défaut dans le joint d'arbre (ou la pompe est toujours en cours de rodage). J'espère que cela pourra vous aider. Sinon, veuillez nous recontacter. Bien cordialement, Sabrina

This is only the easy part. If you are replacing seals, then there is a good chance they've leaked and bearings will need replacing. How about another video to show removal of rotor and bearings as well as dewatering the stator unit.

@grundfos 2 жыл бұрын

Hi, Thanks a lot for your comment:) The reason is that for Scala2 we do not offer the rotor/ bearings and stator as spare parts. This is due to the high risk of flooding the stator if not done correctly. Wish you a great day:) Kind Regards Pernille

The day it leaks again and it's not under warranty I will DEFINITELY look for a differnt manufacturer. Look at how many views this video got. It's obviously a problem

@grundfos 2 жыл бұрын

Matthew, feedback like yours helps us identify and make appropriate corrections - to ensure the SCALA2 reaches its full potential by providing our customers with perfect water pressure. It should be noted that the SCALA2 and SCALA1 are completely different pressure boosting systems. The SCALA2 is a variable-speed pump that provides constant pressure in the system, designed for pressure boosting for domestic applications, such as one- and two-family homes and apartments. Integrated speed control allows the SCALA2 to maintain constant pressure in the taps. The SCALA1 is a fixed-speed pump designed for pressure boosting in domestic water supply and light-commercial applications, such as sports field irrigation or garden irrigation. I hope this is helpful. - Kind regards, Joel

@@grundfos Il rivenditore ha già sostiuito la prima l'anno scorso. L'ho ricontattato: non tratta più Grundfos proprio per i troppi problemi con questo modello. Gli altri 4 che mi avete segnalato idem. Il più vicino è a 100 km. Ma il problema è un altro: in presenza di un evidente problema di progettazione e materiali, Grundfos dovrebbe ritirare il prodotto e fornirne uno nuovo. Basta cercare su KZfaq per trovare decine di casi con identico problema. Ma il posto giusto per parlarne non è questo. Ho scritto e telefonato ma non c'è stato verso di affrontare il problema.
