This depends on the type of pool.
Above ground pool water level for winter.
Winterizing your pool may seem complicated but with a little preparation it can be.
You must keep at minimum a few inches of water usually six to 12 inches is safe covering the floor of the shallow end of the pool at all times.
The skimmer is also a resting place for larger pieces of dirt and debris that are blocked by a skimmer basket.
Properly winterizing your pool will protect your equipment from ice damage keep your water clean and will help save you time and money when opening your pool in the spring.
Water enters the skimmer and moves to the filter through hoses or pipes and back out from the filter into the pool through return jets.
But as a rule if temperatures typically drop and stay below 65 f 18 c during the off season wait until the temperature falls below that point to close.
Draining an inground vinyl liner pool for the winter.
In addition it is preferable to leave the a good water level in the pool with rain and snow.
Adjusting the chemical levels in your above ground pool helps balance the water and protects your pool from scale buildup and corrosion.
This way the pool will retain its shape and prevent water spillage on the ground.
Most pool professionals agree that the water level in both in ground and above ground pools should be at the midpoint of the pool skimmer.
In general it is not recommended to fully drain the pool during the winter.
The skimmer is responsible for providing a pathway for water to flow to the filter where it is cleaned.
The calcium should measure between 175 and 250 ppm and the chlorine level should read between one and three ppm on a test strip.
When to winterize your above ground pool depending on where you live your closing times will vary.
Due to the mechanics of how a vinyl liner is installed into an inground pool this water level represents the normal safe level beyond which you can expect to damage.
Above ground pool for above ground pool it is best to lower the water up to 18 below the skimmer.
The desired ph is between 7 2 and 7 6 and the alkalinity should be between 80 and 120 parts per million or ppm.
Therefore it is necessary to lower the water level at the close at a certain level.
