One. What is the diameter of the water tap hole?
The opening size for the water filter faucet is 15-20mm. It can be installed using the existing soap dispenser hole in the countertop (stainless steel). If there is no soap dispenser hole, a new hole must be opened and installed. The opening size for the water filter faucet is 15-20mm. If the customer has a marble, ceramic, or countertop, it is recommended that they open the hole themselves, as these materials are more difficult to drill.
Two. Methods for drilling holes in faucets.
1、Single-hole
A single-handle faucet, as the name suggests, is a faucet with only one outlet. Because it uses two thin, flexible hoses connected to a single faucet, it may feel that the water flow is limited. Single-handle faucets with both hot and cold water outlets are commonly found in kitchen sink high-spout faucets.
2、Double-hole
As the name suggests, a double-outlet faucet has two outlets. These are typically integrated faucets, which are common products with simple and elegant designs. They are easy to adjust, with cold and hot water controlled by either lifting or pressing the handle. The temperature can be adjusted by turning the spout left or right according to the markings. These faucets are ideal for general household use. When choosing a double-outlet faucet, it is recommended to select high-quality ceramic valves to extend their lifespan. Double-outlet faucets can also be installed with separate cold and hot water control faucets.
3、Three-hole
Also known as "separated" faucet, it features an elegant and sophisticated design, suitable for large countertops and sinks. It occupies more space than single or double-hole faucets, and installation is slightly more complex. While it allows for simultaneous hot and cold water operation and provides a large water flow, it may require two hands for temperature adjustment.
