Good afternoon, dear guests and subscribers of the "Build for myself" channel!
Drainage of pools that hold 5-7 cubic meters is a simple process, but what about people who have pools of 30-40 cubic meters? It is very expensive and long to drain / fill in water every time... For many, it is corny, but there is no normal place for storing frame pools - either mice gnaw, then the plastic cakes, melts and deteriorates in two or three seasons, etc. And leaving everything as it is in cold weather is fraught with the loss of the entire structure, especially if the pools are stationary - then the ice squeezes out any walls!
Of course, there are craftsmen who manage to drain large volumes both to neighbors and to the roadway. I wrote about this in one of my articles when I found my neighbor doing this in the late evening. If interested, link to the article: "Oh, you scoundrel" - accidentally saw where a neighbor drains 100 tons of water from his pool.
In this article I will tell you how my friend uses to not drain the pool and this method 100% prevents damage to the walls of the pool when the water freezes.
First of all, before the onset of frost, you need to clean the walls and bottom, and also bring the pH to a normal value of ~ 7.3 - 7.5. Then:
1. Remove hydraulic systems that can be dismantled or completely drained from them, as well as drain the remaining water from all taps.
2. Drain the water to a level of 15-20 cm. from the water supply nozzle or from the edge of the pool bowl (depending on the type of pool).
3. Close all drains with plugs.
And, now you can safely place pressure compensators that reduce the effect of ice on the walls.
Compensators are any things / objects that are easily squeezed and squeezed. As such compensators, plastic 1.5- are most often used; 2-; 5- and 10-liter water bottles, as well as clean plastic canisters.
The main rule is that the expansion joint itself does not rise to the surface when ice forms. This is achieved by using various weighting agents: sand and crushed stone inside the containers (sand fills the container by 1/3). A container with air should be submerged in water approximately 2/3.
It is also important that the containers do not stick to each other due to the surface tension of the water and are distributed over the entire surface. This is achieved with a regular clothesline tied to each bottle neck in 30-50 cm increments. The garland is attached to the sides of the pool bowl.
Many people tie a stone at the bottom as a load to each bottle:
If the owner is often not at home, then so that precipitation does not fall into the bowl and does not overfill it, the pool is covered with a cover and so it hibernates until the first warm days.
Any easily squeezable clean container can be used as a pressure compensator!
I hope the article was useful to you. Thanks for attention!
