The terms you agree to when you buy a machine from us, book a repair, or take an annual maintenance contract.
In effect from 6 September 2026.
Twinsons Water Technologies, trading as FilterXpert, 27/56, Attapara Lane, Sinthi, Baranagar, Kolkata 700050, West Bengal, India. +91 90739 08901 · [email protected].
We tell you the price before we do the work. A quotation is valid for the period printed on it, and we will not add a charge you have not approved. If a technician finds something extra once the machine is open, the work stops and you are asked first — on your phone, in writing, so there is a record of what you agreed to.
Prices include the parts and labour listed on the quotation. Taxes are shown separately where they apply.
We give you a date and a time band, not a promise to the minute. If we are going to miss it, we tell you. If nobody is at the premises when the technician arrives, we may charge a visit fee for the wasted trip, and we will have told you that before the visit, not after.
You can change or cancel a booking by calling us. Please give us as much notice as you can — a technician’s day is planned around your slot.
Payment is due when the work is finished, unless the quotation says otherwise. We accept UPI, cash, cheque and bank transfer, and we issue a receipt for every rupee taken. A cheque that bounces may attract the bank’s charges.
Money is collected against a job or an order, never on account. If somebody asks you to pay in a way that does not produce a FilterXpert receipt, do not pay, and call us.
Parts we fit carry the manufacturer’s warranty. Our labour is warranted for the period stated on your invoice. A warranty does not cover damage from misuse, from work done by somebody else, or from a water supply outside the range the machine is built for.
Every serialised part we fit is scanned onto your machine’s record, so you can see what went in and when. If a part fails inside its warranty, we replace it.
An AMC covers the visits and parts written into it, for the period written into it, at the address written into it. It does not cover a machine we did not install unless we have inspected it first. Contracts do not renew themselves silently — we contact you before the end date and you decide.
Tell us. Call +91 90739 08901 or write to [email protected] and we will put it right or explain why we cannot. We would far rather hear it from you than read it in a review.
How we handle your personal information is set out in our privacy policy, and how to have it deleted is on the data deletion page.
These terms are governed by the law of India, and disputes fall to the courts at Kolkata, West Bengal.
If we change these terms we change this page and move the date at the top. The terms that apply to your job are the ones in force on the day you booked it.
A few quick questions — no long form. We'll call you back, usually within a couple of hours during business hours.
