A 15mm isolating valve (often abbreviated as "iso valve") is a small valve used in plumbing systems to control the flow of water to a specific part of the system, such as a tap, washing machine, or other appliances. These valves are highly useful because they allow you to isolate sections of the plumbing system for maintenance or repairs without shutting off the entire water supply.
Key Features of 15mm Isolating Valves:
-
Size:
- Designed to fit 15mm pipes, which are standard in many domestic plumbing systems.
-
Function:
- The primary function is to allow or stop the flow of water in a section of the plumbing.
- These valves are typically used to isolate a particular fixture or appliance, making it easy to perform repairs or replacements without disrupting the entire water system.
-
Types:
- Standard Inline Isolating Valve: The most common type, with a straight design that fits between two sections of pipe.
- Lever-Type Iso Valve: Features a small lever or handle that is turned 90 degrees to open or close the valve. These are easy to operate and provide a clear indication of whether the valve is open or closed.
- Screwdriver Slot Iso Valve: Operated by turning a screw slot on the valve with a flathead screwdriver to open or close the valve.
-
Material:
- Typically made of brass, which is durable and resistant to corrosion.
- Some may have chrome plating for additional corrosion resistance or aesthetic purposes.
-
Installation:
- The valve is installed inline with the pipe, typically using compression fittings or push-fit connections.
- Installation involves cutting the pipe, inserting the valve, and securing it with compression nuts or push-fit connectors.
-
Applications:
- Under sinks: To isolate taps or faucets.
- Washing machines and dishwashers: To control water supply without affecting the rest of the system.
- Toilets: To control the water supply to the cistern.
- Any plumbing fixture: Where you need the ability to shut off the water supply independently.
-
Operation:
- On/Off: Turn the lever or screwdriver slot 90 degrees to shut off the water flow; return it to open the flow again.
- Ease of Use: Quick and easy to operate, requiring minimal effort to isolate a section of plumbing.
-
Advantages:
- Convenience: Allows for easy isolation of fixtures or appliances, making maintenance straightforward.
- Prevention of Water Damage: Quickly shut off water to a leaking appliance or fixture, reducing the risk of water damage.
- Maintenance: Simplifies maintenance tasks, as you don’t need to turn off the water supply to the entire house.
