How to Select

How to shop for Plumbing valves

Plumbing valves are an integral part of any plumbing system. They maintain the pressure and stop water from leaking. Loss of pressure can result in poor performance of devices requiring water, while leakage may cause expensive water damage.

Although plumbing valves are an inexpensive part of the system when compared to the larger components such as heaters, careful consideration should be given when purchasing these items. Poor quality or ill-fitting valves can compromise the integrity of your system.

The following factors should be consider when purchasing:

  • Size. Choose the size which suitable for the product. Exact measurements are given and valves are designed to be connected to standard equipment.
  • Choice of Material. Valves are available in a choice of metal or plastic. Depending on the configuration of the valve different materials may function better. Westside Wholesale can help with the selection of the most appropriate valve to use with different devices.
  • Cost. Cost is usually an important factor but should be considered in line with quality. Plastic plumbing devices are cheaper but stay very short life of span. Choosing steel plumbing devices save money a lot because they have a very long life, often 25-30 years or more.
