Hydrostatic 40mm and 50mm Valve Removing Tool
Pool builders and service staff us this tool to remove the floor valve allowing ground water to come in there for reducing the chance of ground water pressure lifting the pool whilst empty.
- There is two valves used 50mm and 40mm.
- Over the years all valves underside thread is 50 or 40mm but the top side shape did change so you may have to modify the tool like I have did.
- THE BELOW VALVE IS SUITABLE FOR THIS TOO ( THE OD OF THE 50MM IS 70MM, WERE THE 40 MM is 55MM)
