Frequently Asked Questions

What does the barrel union do on a sand filter MPV?

The barrel union creates a union joint between the multi port valve and the pool pipework, allowing the valve to be removed for servicing or replacement without cutting pipes.

Is this a genuine Davey part?

Yes, this is a genuine Davey spare part supplied by Pool Systems.

Will this fit my Eco Pure or Reliance MKIII filter?

Yes, this barrel union suits the 40mm (1.5") Monarch MPV used on Davey Eco Pure and Reliance MKIII sand filter systems.

Do I need to replace the whole MPV or just the barrel union?

In most cases, replacing the barrel union alone restores a watertight connection without needing a full valve replacement.
