Assuming there are no leaks in the Plumbing or structure of the pool and trough, there are several factors to consider.

If the vanishing edge pump runs daily for any period of time, then the effects of evaporation over the entire surface of the pool will be noticed in the water level in the trough. For example, if the pool is ten times wider than the trough, or has ten times the surface area, then a 0.2"/day water loss/day in the pool due to evaporation would result in a 2" drop in the water level in the trough. This doesn't include the normal water loss in the trough itself due to evaporation or the additional evaporation caused by having a thin sheet of water flowing down the face of the vanishing edge feature, or by water that splashes out of the trough due to wind or poor design.

If you're losing more than 4" per day in your vanishing edge trough, I would suspect a leak somewhere in the system. The leak could be in the pool plumbing or structure or in the vanishing edge trough structure or plumbing.

To see how much water you're losing in the trough, run the pump until the pool overflows into the trough, then turn off all the pumps and wait about 5 minutes for the water level to stabilize. Mark or measure the water level in the trough. Do the same thing 24 hours later - this way you're comparing apples to apples. Of course turn off any autofill devices during the test.

If you think you have a leak, call a pro like American Leak Detection to test your pool.

How can you calculate the evaporation rate of your swimming pool?

To calculate the evaporation rate of your swimming pool, you can use a simple formula: Evaporation Rate = (Pool surface area) x (Evaporation rate factor) x (Temperature difference). Measure the surface area of your pool, find the evaporation rate factor for your area, and determine the temperature difference between the pool water and the air. Multiply these values to calculate the evaporation rate.

Would heating or cooling a pool decrease evaporation?

Heating a pool will increase the rate of evaporation from that pool.

What is the evaporation rate of a solar pool heating system on a swimming pool?

Approx. 1.5" to 2" per wk.

Will a darker pool liner cause more water evaporation?

A dark pool liner might cause a very small increase in water evaporation, but nothing significant. The dark pool liner will raise the water temp a bit which, in turn, may increase the evaporation rate. But, the evaporation rate is much more dependent upon the air temperature and humidity than on the water temp, so the increase in water temp would only have a very small effect on the overall or net water evaporation rate. Hope this helps ... yes, it will, and it could be a significant increase.

How much water should a pool lose in April?

The National Weather Service uses a large water pan with a diameter of 4 feet. They measure the drop in water level in one day, fill it back to the level it was before and measure the level drop the next day. They and others do this all over the United States. Others do it throughout the world. The Weather Service reports the evaporation at each location, each day, and sum all these daily values up to obtain an annual evaporation rate in inches. All the data through the US is collected and compiled into an annual evaporation map. Looking at the annual evaporation map one can find the average annual evaporation rate for any location. It is roughly 100 inches for Tucson, Arizona. The evaporation rate varies with temperature, wind speed, sunshine, and relative humidity. The evaporation rate also varies throughout the year. A rough daily rate is given by dividing the annual rate by 365 days. Rough daily evaporation rate = Annual Evaporation rate / 365 For Tucson the rough evaporation rate is 100 inches/365 which is about 1/3 inch per day. Swimming pool If we use this rough evaporation rate, we can find how much a swimming pool water level might drop in 5 days Total surface drop = (5 days) (daily evaporation rate)

How much water evaporates from a pool in Phoenix?

Eventually, all of it if not replenished. The rate of evaporation depends on local climatic conditions.

What happens when the rate of evaporation of a liquid as the liquid is cooled?

Rate of evaporation depends on temperature. As Temp decreases, so does the rate of evaporation.

How a warm day affect rate of evaporation?

The rate of evaporation increases

What is the average rate of evaporation of an outdoor pool in Texas?

The evaporation rate of an indoor swimming pool has many factors to consider. 1.) How large is the pool? 2.) What temperature are you keeping the pool water at? 3.) What temperature are you keeping your poolroom at? 4.) Are you using a pool cover? An example would be..... If you have a 300 sq. ft. pool and are keeping the pool at 82 degrees and the room at 84 degrees your evaporation rate would be 10.35 pounds per hour at a static level (no activity). If you do have an indoor pool or are considering having an indoor pool you will need to use mechanical dehumidification to handle the evaporation rate of your pool to protect the structure. Please email me direct if I can further assist you in that area. Regards, Michele Environmental Pool Systems

How does temperature affect the rate of evaporation?

The higher the temperature, the higher the rate of evaporation. It is

What conditions will increase the rate of evaporation?

Heat speeds up the rate of evaporation.

How fast will the water evaporate in an above ground pool?

It depends on whether the pool is considered "enclosed" inside a pool house or not. The assumption in such case is that the pool house prevents "outside" air circulation which enables the humidity inside that "house" to be maintained at a high level which minimizes evaporation. It goes without saying then that if you keep the doors to your pool house open then you loose much of the evaporative benefit of having the pool enclosed. In any case, high ambient outside air temperature will increase the pool evaporation rate but an enclosure should slow it down. Pool covers can also decrease evaporation rate. More input from FAQ Farmers: * Go to Arizona edu. There you will see a contour map of the U.S. providing annual evaporation rates in inches of loss per year. Find the rate for your area. Divide the rate by 365 to get the daily rate in inches of loss per day. * If you are concerned of a leak place a bucket of water on the steps of the pool and fill it so that the level equals the pool(u might have to weigh the bucket down with a rock or something) check the level the next day to see if they both evaporated the same.
