Oase Pump Vault Extension 55000 – Legacy 72951

Oase Pump Vault Extension 55000 – Legacy 72951

Original extension section for deeper Oase 55000 pondless pump-vault installations

This is the original Oase 72951 Pump Vault Extension 55000 listed by the supplier. It raises the access height of the matching earlier-generation 55000 pump vault, allowing that chamber to reach through a deeper reservoir or thicker finished landscape layer.

A pump-vault extension does not increase pump performance or reservoir volume by itself. Its purpose is service access. Measure the existing chamber, identify its Oase part number and check how the extension locates and seals before ordering. If you are designing a completely new installation, compare the current Oase Pump Vault 20000 and current extension components rather than assuming old and new parts interchange.

Good installation practice

• Confirm the original vault model and part number.
• Keep the completed opening large enough for the pump and fittings to pass through.
• Support surrounding stone or paving independently.
• Prevent loose gravel and soil from falling into the chamber.
• Maintain safe access to electrical isolation and hose connections.

For the wider concealed system, see Oase Maxima storage blocks and Oase Spillway Boxes.

Frequently asked questions

Will it fit the new 20000 vault?

Do not assume so. This listing is for legacy part 72951 and compatibility must be checked against the exact vault.

Why use an extension?

It keeps the pump chamber reachable when the reservoir is deeper or the landscaped finish sits higher than the original lid.

Is the vault included?

No. This product is the extension component only.
