And here's how to isntall PRIMATO DELUXE 101 tap:

"How do I choose the right cartridge for my water filter?"

Below the "Add to cart" button you can click on "HOW TO CHOOSE THE RIGHT FILTER". A text will appear on your screen summarizing the functions of available replacement filters for this water filter. Other replacement filters fit into your housing as well, but because there are a lot, we only recommend specific filters.

Also, just below the product description, you will see the available cartridges. If you click on the quick view "eye" you will see a summary of the specific cartridge. If you click on the image, you will be taken to the cartridge page where you can see more details. If you have not yet decided which replacement filter is right for your water filter, simply contact us! We will be happy to assist you!

"Should I install a filter on the counter or under the kitchen counter?"

This depends on your needs and the available space in your kitchen. Generally speaking, the countertop filters can be installed in seconds, but they take up space on the kitchen counter. Under-sink filters do not require space on the bench, but they need skilled hands for installation or even a plumber.

"I do not know if I need a single, double or triple filter"

If you are having problem with your water's bad taste and odour, then you need a single filter. But if you also have a lot of dirt in your water, then you need a double filter - the first stage will be a filter for reducing mud and the second one an activated carbon filter for reducing chemicals. But if you have 3 problems (eg hard water, mud and bad taste), then you need a triple filter, one for the reduction of scale, one for the mud and one for improving taste and reducing chemicals. If you use drilling water then you need a reverse osmosis filter. Whatever problem you are facing with your water, if you are not sure, just contact us! We will be glad to find the right water filter!

"How do I remember when to change my cartridge?"

Forget abou it! When it's time to change your cartridge, we'll call you or email you to remind you!

"If some part of the filter breaks, do you have spare parts?"

We have all the parts you may need for your water filer.

"What does the warranty include?"

In order for the warranty to be valid, you must maintain the filter correctly (of course it's not valid if you break it yourself and you should use the cartridges displayed in our website. If you clean your water filter internally every time you change the filters and if you change the filters at the scheduled time, your water filter should last for many, many, many years. If, however, your water filter has a problem of our own fault, (even if it was damaged during transportation) , we immediately take it back at our own expense and send a new one as soon as possible.

"I have lost the wrench and can not unscrew the device to change the cartridge"

We have all the parts you may need for your water filter, including the wrench. Feel free to contact us for assistance.

Έχετε παραλείψει από την προσφερόμενη κατασκευή σας, τους προηγούμενους κατοίκους οικιών που έχουν μαρμάρινους νεροχύτες και χρησιμοποιούν μέχρι τώρα προηγούμενο Φίλτρο Ανω Πάγκου. Ο αριθμός αυτών, είναι πολύ μεγάλος και θεωρώ ότι η ποαράλειψή σας βλάπτει και εσάς και εμάς. Επιθυμώ το δικό σας Φίλτρο σε Άνω Πάγκου.

Απάντηση από την ομάδα της Primato: Κύριε Αννουσάκη, δυστυχώς αυτή η εταιρία δεν βγάζει τετραπλό φίλτρο Άνω Πάγκου. Μπορούμε βέβαια πολύ εύκολα, στο τριπλό φίλτρο άνω πάγκου αυτής της εταιρίας, να αντικαταστήσουμε ένα από τα φίλτρα ενεργού άνθρακα με φίλτρο αλκαλικών. Παρακαλούμε επικοινωνήστε μαζί μας στο 2310 383 588 ή αφήστε μας κάποιο email με το τηλέφωνό σας για να σας πάρουμε εμείς. Σίγουρα θα σας βρούμε την καλύτερη δυνατή λύση και θα χαρούμε να σας εξυπηρετήσουμε!

Πολύ καλή βρύση, σε άλλα φίλτρα που έβλεπα τα βρυσάκια ήταν κινεζίλες. Είναι πολύ προσεγμένη δουλειά (συσκευασία - κουτί - ποιότητα κτλ). Ο υδραυλικός χρειάστηκε περίπου μισή ώρα για τη σύνδεση. Το νερό πολύ καλό όντως.
Ελένη Παπαγιαννοπούλου
Θεωρώ μεγάλο πλεονέκτημα την εύκολη αλλαγή των φίλτρων γιατί με τα πιο "παραδοσιακά" φίλτρα που είχα παλαιότερα είχα δυσκολευτεί. Το νερό είναι πολύ καλό και από άποψη γεύσης και από άποψη μυρωδιάς.
Γιάννης Μηνάς
Αρκετά διακριτικό σαν μέγεθος σε σχέση με αυτά που προσφέρει. Στα συν της εταιρίας η πολύ καλή τηλεφωνική εξυπηρέτηση. Από παράδοση είναι αρκετά γρήγοροι, το έστειλαν την ίδια ημέρα και μας ήρθε την επόμενη.
Γιώργος Καραβόπουλος
Μας ήρθε την επόμενη ημέρα. Πολύ δυνατή τηλεφωνική εξυπηρέτηση. Μου άρεσε ιδιαιτέρως που μπορώ να βάζω άλλα ανταλλακτικά φίλτρα της αρεσκείας μου στο μέλλον ανάλογα με το πρόβλημα της περιοχής. Το νερό μέχρι τώρα είναι πολύ γευστικό.
