Plumbing sizes can be confusing. Pressure PVC pipe use nominal sizes - the size is simple a name, not the measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.
- 50mm / 2" = ~60-61mm OD
- 40mm / 1.5" = ~48mm OD
- 25mm / 1" = ~33-34mm OD
