A technical diagram for the swimming pool pump room is necessary or even compulsory for anyone planning to build a swimming pool. Why? Because the filtration group, the real engine of the pool and therefore the most important part, is installed there; if you think about it, what would the pool be without the filtration system: a tank, made of concrete, blocks or any other material, which contains water. If the water is suitable for swimming, it is because of the filtration and the water treatment equipment.
What is the purpose of a diagram of the pool technical room?
Making a schematics of the pool filtration system has several advantages:
– Do not oversize the swimming pool pump room that will house all the equipment.
– Facilitate the installation of the different devices: pump, filter, heating, disinfection, …
– Place all valves at the right location
– Understand how your pool works
– After construction, have a document to refer to in case of malfunction.
We advise to combine this plan with a diagram of the piping layout from the pool to the technical room.
How does filtration system work ?
A swimming pool, whether it be a skimmer or an infinity pool, operates in a closed water circuit; this means that the same water is always in the pool. The water is sucked by the pump and then pushed to the filter where it is cleaned of dirt such as dust, pollen, hair. It is then pumped back into the pool after having been disinfected and heated if necessary – this is called the filtration cycle. All the water in the pool must be filtered approximately every 4 hours.
What is fitted in the swimming pool pump room ?
This generally enclosed space is designed to receive the various equipment of the filtration system:
- The filtration pump
- The sand, diatomaceous earth, glass media or cartridge filter.
- The disinfection system, a salt chlorinator for example.
- The heating system or its connection when using a heat pump installed outdoors.
- The electrical board in charge of controlling all these different appliances.
All this equipment must be protected from the weather and heat; a well-designed technical room must be easily accessible to the user to facilitate maintenance operations but shouldn’t accessible to children. Various options are available, these are outlined below.
Where is the swimming pool pump room to be installed ?
A well-located pump room saves money: fewer pipe lengths, a well-calibrated pump avoiding pressure losses, etc. Adjacent to the pool is the best option but other solutions exist. We advise to place it near the pool and never more than 10 meters from the pool to avoid pressure losses.
The underground or semi-underground swimming pool pump room can be made of masonry or concrete but there are also prefabricated polyester pump rooms. It is better to locate it, or at least the pump, below the water level and the valves must be easy to handle.
The above ground technical room can be a dedicated construction or an existing room close to the pool.
The pump room integrated in the pool is located in a ladder, for example for the Desjoyaux swimming pool brand. Usually, no additional equipment can be added to it and no pool pump room diagram is made.
Sizing it as accurately as possible
Before drawing the swimming pool pump room diagram, it is important to confirm the dimensions of the room itself.
It should be remembered that below 2 m2 no authorisation is required in France. From 2 to 20 m2 a “Déclaration préalable” for minor works, possibly the same as for the swimming pool, must be filed. Above 20 m2 a building permit will be required. If you wish to know more about the French regulations, you can find more information here.
2 m2 seems enough for a skimmer pool, but an average surface of 4 m2 is usual for an infinity pool; the main thing is to design a pump room where you can house additional equipment later on.
Many people recommend using the pump room to store chemicals; we don’t do it because it can damage the equipment even if the room is well ventilated.
Drawing up a diagram of the pool technical room
This plan must be carried out after the piping layout from the pool to the pump room. Indeed the positioning of the pipes and valves depends partly on the entry into the technical room. Therefore each plan should be unique; if you would like us to guide you through this installation, please contact us.
Positioning of the filtration unit and optional equipment
Depending on the the pipes coming from the pool, the pump and filter will be placed to save pipe lengths, elbows and tees and make the best use of the available space. The filtration system is of course perfectly calibrated taking into account the volume of the pool, the position of the technical room, but also the climatic conditions and the number of bathers, at least for those receiving the public. All this is easily done by means of simple calculations and by using the pump efficiency curve, which differs from one manufacturer to another, even for the same output.
Connection of the various hydraulic and electrical components
Pipes and electrical cables are shown to facilitate the installation of all equipment in the pump room.
Location of valves and other safety devices
Valves, like a tap, close off the flow of water and are therefore essential for filtration running, isolating part of the hydraulic system for further repairs or equipment changes. For an overflowing pool, the correct positioning of the non-return valves is crucial to prevent accidental draining of the pool.
An example of a diagram for a swimming pool pump room
Below is a very recent filtration carried out by a plumber in Asia, who is not a pool specialist, based on our plans.
The private infinity pool measures 10m x 6m.
The equipment includes :
A filtration unit of 2 CV and a filter with recycled glass.
The balancing tank is equipped with an automatic water supply and safety floats for water levelling.
How do you envisage the installation of your pool’s filtration system? If, like some of our customers, you have a general plan but nothing regarding the installation of the filtration system for your pool, our custom-made hydraulic plans should be useful.
