I bought a house with an indoor pool that I know nothing about. It appears to be concrete, painted with a white paint. It's said to be built in 1970s. There's a pump that's running round the clock, the pool is covered with a plastic membrane (to reduce evaporation and dirt to getting in -so I'm told). I'm tempted to turn that pump off as it's kid of loud, but don't want to mess anything up.
Where do I begin? Contact local pool maintenance company? Any tips are appreciated.
