New pool owner, first leak!

[tobitoy]

So we bought a house with a fibreglass pool thats about 10 years old. Last year it worked fine but this spring i detected a leak. Confirmed by the bucket test.

For winter shutdown I emptied the pool below the inlets so I don’t suspect the lights to be the issue. However today I discovered small cracks in the skimmer faceplate. They are small but could this be the source of the issue? I’m loosing about 4mm per 24hrs with pump shutoff. The pool is 8x4m.

I have inspected the connection between skimmer and main drain and there is no leak there.

Welcome to TFP.
Cracks in the skimmer faceplate can be an issue. Is the pool now filled to the middle of the skimmer?
You can do a dye test by using a syringe with a food color dye. Squirt it near the crack to watch if it is sucked into the crack.

Do you have 1 skimmer or 2?

 

[tobitoy]

Yes, filled to the middle. And one skimmer. Will try with dye
