Frequently Asked Questions

Straightforward explanations of our brassware servicing, valve overhauls, and pipeline repair methods. We explain what we do before touching a single fitting.

1. 1

   how to choose the right brass valve size

   Measure the external pipe diameter or check the stamped thread markings on your existing fitting. Our technicians confirm the millimeter dimensions against CW617N brass specifications before booking your installation. We ensure thread standards match British Standard Pipe sizing.

2. 2

   what is cw617n dezincification resistant brass

   CW617N is a certified European brass alloy engineered to prevent zinc loss in warm or acidic water. This metallurgy stops the fitting from turning porous or brittle over years of service. It maintains structural strength under high system pressures.

3. 3

   can you service a flat without a lift

   Yes, our Cardiff specialists carry tool cases and boxed fittings directly up stairs to any floor. Please notify us during your booking if access requires gate codes or specific parking permits. Same-day Cardiff technician dispatch is scheduled for bookings confirmed before 11:30.

4. 4

   how is payment handled after job completion

   Payment takes place directly upon completion of the work on site. We accept cash upon completion or direct bank transfer immediately following inspection. We do not accept card payments.

5. 5

   whether an invoice is issued with vat

   We provide an itemised written invoice with full VAT breakdowns for every completed job. The invoice lists the installed CW617N brass parts, seal specifications, and labour costs separately. We hand over the printed copy on site or send it via email.

6. 6

   what happens if a component does not fit

   Our technicians bring multiple thread adaptors and seal gauges to every Cardiff callout to resolve sizing differences immediately. For unused parts dispatched separately, returns are accepted within 30 days from delivery if they remain unused in their original packaging. Return transit costs are covered by the client unless the item was supplied incorrectly.
