We have collected a few questions and answers for you about swimming pools, installing them and maintaining them:


Article: "Appeals committee: adding a pool to a back yard, even if it doesn’t appear on the valid city plan is allowed 

Question: I have a 100 cubic meter pool. I have added a salt machine to it that works 8 hours a day. Every week when I check the chlorine level in the pool, I find that there is chlorine missing, so I add liquid chlorine.

Is it possible to add chlorine when the machine is on?

Answer: first of all- the salt machine needs to be on at least 10 hours a day. In the winter you can have it on for 8 hours. Second of all- you need to check your stabilizer level and the salt you have in the water, and if needed add some. You can check this with the test kit. Additionally, you need to adjust the intensity of the machine, you may need to turn the power up and by this intensify the production power.


*question: I'm interested in advice about changing the vinyl in my back yard swimming pool. Sometimes ordering new vinyl lining takes weeks and the existing vinyl can tare in the meantime. I know you shouldn’t leave the pool empty without water,

What should I do?

Answer:  If your vinyl is torn- change it immediately. First lower the water level to the height of the tear. If the tear is below the skimmer level, you must shut down the skimmer taps and leave only the floor suction on, this way the water circulation will continue. About changing the vinyl itself- it takes time and with our company we can change the vinyl for you within a week. Contact us and we will give you a quotation, specific instructions for the meantime until we change the vinyl and we will set you a date to come and change it.  


*question: I own a swimming pool and have small children at home. I always worry that when I'm not around one of my children will slip and fall into the pool. Are there any products that can prevent children from falling into the pool?

Answer: we have a number of safety products in our company. The most efficient and safest solution is an electrical pool cover.

This cover closes the pool and can resist weights up to 2 tons. Additionally we sell a special European net fence that prevents people from entering the pool area.


Question: I'm in the midst of building a house and I am interested in putting a pool in my garden. I know that there is a wide range of swimming pools and I am interested in knowing the differences between them and what are the costs?

I would also like to receive a proposal from you for a few models and then I could contact you if I'm interested.

Answer:  There are two types of swimming pools: concrete pools and industrial pools. A concrete pool with ceramic cladding is the most expensive pool. This kind of pool will cost double as much as an industrial pool. Our advice is, while you are building your house, speak to the contractor and ask him to pour concrete in the pool, this way you will save on concrete costs. In this case, where a private contractor will cast the pool, we will accompany him with consultation, and while he builds the cast, we will accessorize the pool with whatever it needs. Afterwards, the contactor can cast the pool. After cladding the pool with ceramics, we will build the machine room and activate the machines in it. If you have built an industrial pool, you won't be able to tell the difference between it to a concrete pool. The pool is then covered with vinyl lining printed with mosaic, and like this the pool looks like a concrete pool. The construction time for an industrial pool is about ten days.      



Question: I am planning to build a pool in my back yard. Can you give me a financial evaluation of electricity cost, water, chemicals and hours I will have to invest in taking care of it?  

Answer: The electricity consumption of a swimming pool sums up to about 130 NIS a month. This obviously depends on the type of electrical pump we use while building the pool. We use HAYWARD economical electrical pumps with the Israeli standards association stamp. The cost of the chemicals (chlorine and salicylic acid) is about 120 NIS a month. You can save on these costs if you add a salt machine, and then chlorine is not needed. A salt machine disinfects, saves you the chlorine costs, and saves you the chlorine smell and the effect of burning eyes for who ever goes in the water. The cost of a salt machine is between 1400- 1800$, depending on the size of the pool. About the hours you need to dedicate to taking care of the pool, its up to 30 minute a week.   


*question: Is there a device that checks how much chlorine I need to add and makes sure there isn't too much of it, so it doesn't harm my children etc? I know there is the color set, first of all how do you use it? How long does it need to be dipped in the water for? And how long does it take for the color to show an answer? Is it precise? And is there a device that shows precise numbers?

Answer: The color check set is precise and you can trust it without worrying. It's enough to dip the whole stick in the water and then to take it out. There is no need to leave it in the water for a while. The color data will appear within a few seconds. There is a digital device to check the water values. This device is very expensive, and that’s why it's mainly used for public pools which need to have an exact documentation of the water values.    



*Question: I have used up all the building percentage that I have. Is it necessary to get an approval for building a pool in the garden? Or is a pool considered part of my building percentage? And is there a difference between the permissions you need for an industrial pool to the ones you need for a concrete pool?

Answer: your building percentage is not relevant to building a swimming pool. Therefore even if you have used up all of your building percentage, this won't block your opportunity to build a pool in your garden.   


*Question: Do you have a comparison of advantages and disadvantages of an industrial pool compared with a concrete pool?

Answer: The only advantage of a concrete pool compared to an industrial one, is in the way it looks. There is no doubt that in its first years a concrete pool with a nice ceramic or mosaic cladding looks very luxurious.

With a concrete pool you can build an overflow edge, which isn’t possible with an industrial pool. Although an industrial pool is much cheaper than a concrete one, if the industrial pool is built correct and the newest equipment is used, you won't be able to tell the difference between it and a concrete pool. Another thing is the time it takes to build. Building a concrete pool takes about 60 days and building an industrial pool takes only 10 day.


*Question: Is there a fixed price for every square meter of swimming pool? For a concrete one and an industrial one.

Answer: there is no fixed price for building a pool, because the equipment used changes depending on the size of the pool and that effects the price.

 However, you can roughly calculate 3,500 NIS per square meter for a concrete pool, while an industrial pool will be about half that price.

This is only correct for swimming pools sized 40 square meters and more.  



*Question: How do I maintain a right acidity level in my swimming pool?

Answer: the acidity level is controlled with salicylic acid for lowering the PH and soda for raising the PH level. Naturally the PH level rises. The amount you need to add, depends on the water level and the results of the test. The ratio for lowering, is to add 1 liter of salicylic acid in a 32% concentration on every 33 cubic meter when the result is 8.2 PH, any other result is according to the ratio of water level to the PH level. For example: a 100 cubic meter pool with a PH level of 8.2 would need an adding of 3 liters of salicylic acid. You need to measure precisely and poor by the inlets, while the pump is working.
