Weather conditions need to be nearly perfect in order to drain a pool. Pool pros suggest 85 degrees is the best temperature to drain a pool. In-ground pools can blister or crack when drained in high temperatures.
"A lot of the finishes in the pools will come loose, de-laminate, pop," he said. Norlock said the ideal time of year to drain your pool is not during the summer, but rather "from fall till early spring."
So if you have the option, it's best to wait for the cooler temps and shorter sunlight hours in the fall and spring to drain your pool. Anything below 85 degrees Fahrenheit (30 degrees Celsius) is considered OK. However, if you have an in-ground pool, there are two other climate-related factors to consider.
If you drain your pool during the hot, dry Arizona summer months, you risk causing expensive damage to your swimming pool . The floor of the pool can crack due to the heat and lack of moisture.
If you have hydrostats in your pool, never drain the pool without opening them. The other danger from hydrostatic pressure is the weight of the water around your pool. If the water table is higher than the floor of the deep end of your pool, water in the ground around your pool will put pressure on its walls.
On both inground and aboveground pools, the liner can shrink when the pool is drained, then tear when the pool is refilled. Refilling promptly and shifting the liner in the early stages of refilling can mitigate this. This is not a good idea with older liners.
Pools need to be drained throughout the mild seasons to avoid unneeded sun, warmth, or dampness damages to the swimming pool surfaces as well as filtering systems. In mostly all situations, swimming pools must not ever be drained for cleaning, as this can be done under water.
Pools in perfect working order will naturally lose water over time. It's typical for residential pools without a cover to lose up to a quarter-inch of water per day during the summer.
The best time to drain the swimming pool
Too cold or too hot weather can seriously affect an empty pool and cause cracks in the liner. Most homeowners decide to do it in the spring so that the pool is ready for summer activities. It's also OK to do so in early autumn when temperatures are still mild.
That's because hot weather heats up swimming pool water where it then increases evaporation, depletes chlorine levels and messes with pH levels – all of which creates the perfect environment for algae and bacteria to grow.
In most cases, very little to no damage will occur to the lawn when a pool, hot tub, or other chlorinated water source is emptied on it, provided it is not done frequently, dumped all in one spot, and care is taken to reduce the chlorine concentration as much as possible from the typical range for a pool or hot tub (1 ...
According to The United States Water Fitness Association, water temperatures for younger children and the elderly will generally need warmer temperatures ranging from 84 to 94 degrees Fahrenheit, while a comfortable pool temperature for adults is 85 to 89 degrees.
90-92 degrees is the highest recommended temperature, well-suited to elderly swimmers or infants.
Draining your pool into the sewer system allows water to be treated and reused. If you have a septic tank, do not drain your pool into the tank. automatic water fill valve. in the ground and close to the home, often near a water spigot.
The answer to this question, no, it's not okay to drain your pool and leave it empty! In fact, you really shouldn't be draining your pool unless absolutely necessary!
Unplug the pool pump and any other electrical components so they can't turn on. Attach enough garden hose to get from the pool to the drain point (sewer cleanout line, the road, downhill, or wherever else you're legally allowed to discharge water). Attach the hose to the submersible pump and lower it into the pool.
Draining or emptying your pool of water can create a number of financial and structural headaches, including: Cracking the pool's shell. Damaging the interior lining or surface. Damaging the pool's coping and surrounding paving or timber work.
For inground pools with a sand or DE filter, the easiest way to quickly lower the water level is to place the multiport valve into the waste position and roll out the backwash hose. If instead, you have a slide (push-valve), backwash the filter to lower the water level.
You can leave a pool empty for 15 minutes at a push, but you should not leave a pool empty unless absolutely necessary due to the risk of structural damage. Pools are designed with the weight of the water to keep it intact. If you do need to drain a pool, you need to move quickly.
Pool Is Losing 1 Inch of Water Per Day
Losing more than ½” of pool water per day indicates you likely have a leak in your pool's structure or your pool pump system.
The differential that occurs between the pool water temperature and the air temperature on late summer nights causes water to evaporate at an accelerated rate. In some cases you might see a water level difference of 1-3 inches overnight.
The water flows into the skimmer at a higher level, it causes the water to not get skimmed properly. This leaves more debris in your pool, and it can cause the debris to wind up getting pumped into the wrong hoses. If the debris goes into the hoses of the pool, it can cause the hoses to get clogged.
And finally, partially draining out your pool will reduce all your chemical levels which include cyanuric acid, phosphates and others that are contributing to the cloudiness and the algae in your pool.
If you have a typical rainfall, or even several inches, your pool should be fine, since drains and skimmers are designed to remove the excess water. In most cases, your pool can even handle rain from most tropical depressions and hurricanes.
