Greetings all, hope everyone had a great thanksgiving ! I have a question regarding topping off water levels for a new hot tub. I have a 2013 Hot Springs Sovereign. I just topped off the water level on 11/13 and looked at the water level today and it needs to be topped off again. I don't see any leaks outside near the tub. Since its winter, there is a lot of steam coming off the tub when open . Hot Springs says to fill water level to 1.5 inches above the highest jet. I know there is loss due to evaporation, my question is this normal, should i be looking more closely or is this normal for hot tubs, I have had 3 hot tubs in my day and they all seemed to need topping off. I have been using the tub more than normal, so is this loss, due to evaporation and some slight splash ? All replies are welcome.
