Hi Guys

I have noticed in the last 2 to 3 weeks that i have been losing water at a rate of about 1.5 cm in a 24 hour period.
The pond gets around 6 hours of sunlight and is 25000lt in capacity.
Being mid winter and pond temp 10 degrees i find it strange to loose that much water. If it was mid summer a different story.
My question is can you get *evaporation* in winter, is it normal ,and is anyone else also experiencing water loss in winter?

Thanks
Anver

Hi Guys,

Me too, but I think it is not evaporation it probably is a small leak as a result of the cold weather.

Evaporation and warm weather go hand in hand. Easy to test though, just fill a bucket to a line, place it by the pond, and check it out. Will do mine tomorrow.

Another posting by Einstein lol!

Sometimes we just get too technical and miss the small things

Hi Oom Neville,

Surely just leaving a bucket of water would not yield the same result as a pond that has a waterflow via a waterfall feature?

The water return would aid in evaporation, where I suspect a free standing bucket has nothing similar you will not get the same result.....maybe do a submersible pump flowing over a tile back into the bucket if you want something more accurate........get surface area also counts....interesting to see tho.

Hi guys

Thanks for the replies so far.
It makes me feel a little at ease as the last thing i want is to find that i now have to look for a leak.
I will still monitor and see if there is changes as the weather patterns also change .
Will keep you guys posted.

That is a leak. With our current cold weather one would not loose that amount of water due to evaporation.

You may loose 1.5-2cm of water on a warm sunny day with a wind blowing but not in winter. There is enough moisture in the air to prevent evapuration.

lol, do you loose water on a rainy day aswell. Razz

What is the length and width of the pond?
Length x Width x cm dropped x 1000 = liters of water missing.

Now go and calculate the amount of water missing and think about it...if its 100l + then there is no way its evaporation...

Splashing water does not = evaporation. Splashing water = a leak

In my pond 6.5m x 3m x 0.01m x 1000 = 195 Liters.....thats alot of water to loose to evaporation.

Hi Ogidni,

I tend to agree with you, Found that the cold weather opens up those fine cracks or places where only the sealer was doing the sealing.

Unfortunately I doubt if it will seal itself again when it gets warmer.

Will have to wait and see

Hi Martin
That's serious. Have you at least found the leaks? I gather that you have because you refer to "two". Structural or plumbing?
..and what have you done with your nice fish?
Regards
Jack

Hi Jack

The one leak is a cracked pipe between the settlement chamber and the filter system. I thought that was the main problem till the pond itself drained out completely. Thank goodness its not a major structural problem and just a leak around the bottom drains. The water proofing is peeling off around it.

The fish are in a porta pool at the moment.

A little tick don't know if any knows it-Is to use dye and put the dye through every pipe and where to ground is colored. You have a leak
