FAQs
Is this valve suitable for central heating systems?
Yes, it is suitable for use in standard water-based residential and commercial plumbing systems, including heating circuits.
Does this valve require any special tools?
Standard plumbing spanners or an adjustable wrench are sufficient for tightening the compression nuts.
Can I install this in a vertical pipe run?
Yes, the valve can be installed in either horizontal or vertical pipe runs, provided there is enough space to operate the handwheel.
Is this product WRAS approved?
Yes, the Primaflow VPG Pump Valve is WRAS approved, meeting necessary UK water safety regulations.
What is the primary benefit of a gate valve over a ball valve?
Gate valves provide a full-bore flow path when fully open, reducing flow restriction compared to some types of ball valves.
Troubleshooting
Valve leaking at the joint
Ensure the pipe is pushed fully into the fitting and the olive is seated correctly. Tighten the nut an additional quarter turn.
Handwheel is stiff or difficult to turn
Check for external debris or scale around the stem; gently clean the area and ensure the valve is not under excessive pipe stress.
Water still flowing when valve is closed
The gate may be obstructed by debris. Gently open and close the valve several times to clear the seat.

Setup, Compatibility & Care
Installation Steps:
- Ensure the water supply is completely isolated and the pipes are drained before starting.
- Cut the 28mm pipe at the desired location, ensuring the cut is square and the edges are deburred.
- Clean the pipe ends to remove any debris or oxidation.
- Slide the compression nuts and olives onto the pipe before inserting the pipe into the valve ports.
- Tighten the compression nuts firmly to achieve a watertight seal, being careful not to overtighten and strip the threads.
- Once installed, slowly open the water supply and check all joints for signs of leaks.
Care and Maintenance:
- Periodically cycle the valve (turn it off and on) once every six months to prevent lime scale buildup on the gate mechanism.
- Visually inspect the valve body annually for any signs of corrosion or moisture at the joints.
