Separate Replacement Work From New Installations
For a replacement, start with the fittings already in place. For a new installation, select the complete fixture combination and its drawing. These two purchasing routes need different information even when the products look similar.
Replacement and Complete-Package Selection| Buying task | Details to record |
|---|
| Hand shower or fixed-head replacement | Existing connection, arm or holder and the required supplied parts |
|---|
| Mixer replacement | Inlet layout, connection centres and control function |
|---|
| Toilet package | Bowl installation, outlet, seat and required flushing components |
|---|
| Vanity and basin combination | Cabinet width, basin layout, mounting and plumbing clearance |
|---|
| Kitchen installation | Sink drawing, tap reach, mounting and accessory scope |
|---|
Review Water Performance on a Comparable Basis
If flow performance is part of the specification, keep the measured flow and supply conditions with the sample result. A low-flow description does not establish performance at low supply pressure. Compare the intended shower assembly under the conditions relevant to the installation.
For filtered shower products, include the selected filter construction and replacement plan as a separate line. Record the performance information needed for the intended product claim, rather than extending a test or maintenance instruction from another model.
Coordinate Bathroom Furniture and Fittings
Review the vanity, basin and mixer as a combination. Keep storage, working clearance and plumbing access visible in the sample or drawing review. For kitchen products, review the sink and tap together while keeping each component identifiable in the quotation.
Send the product references, quantities, receiving location and any project or importer document requirements. Include the requested standards or approval documents for the actual product use so the technical review follows the purchasing specification.
