| medium quality taps.Many tap components

| |
| | key things to consider.1. Unless you have

| (plastic) or an alternative material
| |
| | a very low pressure system or are looking
|
| sometimes referred to as Mazac (Pot
| |
| | for the lowest feasible price then it is
|
| Metal). These are cheaper than using
| |
| | best to go for ceramic disc taps.2. When

| | both taps use the same mechanism. They

| better finish and lasts longer.Standard
| |
| | may look the same, but if one is ceramic

|
| will work at that pressure.As a rule of
| |
| | a third party to verify it actually meets

| thumb many designer taps come from Europe
| |
| | the standard, so an assertion that a
|
| where the water systems have superior
| |
| | product meets BS5412 is only as reliable
|
| pressure than in the UK and these taps
| |
| | as the business making the claim !The

| wont work if you have very low

| the retailer to verify the pressure
