Evaporation or leak

[UKjames]

Given COVID am running the pool later and maybe over winter.

Bit worried my pool has developed a leak. I now seem to need to top it up more frequently than I did in the summer.

If ambient air temperature is lower should I be getting less evaporation not more or is it the other way around?!

I guess bucket test is way to tell but I use a solar cover and am loath to leave it off too long!

If the water temperature is much greater than the air temperature, your evaporation losses will be greater. The solar cover should reduce that loss, however.

Ah thanks Marty, yes the pool temp is largely the same but the ambient temp has dropped from 75 or so to 50 or so.

as you say the cover will reduce it so maybe that’s not the whole reason.

It’s not masses and masses being lost but enough to make me wonder if there is a leak.
