All about home swimming pools
By: Jakob Jelling | Posted: 23rd April 2007
Although home swimming pools might seem very simple, they actually imply several mechanisms which we usually do not know. Although these mechanisms might vary from one home swimming pool to another, there are some basic ones (such as a filtration system and a chemical treatment to clean water) which are usually present in most of them.
A mechanism which is efficient on maintaining the water clean is one of the most important matters which a swimming pool constructor needs to consider. The main components most home swimming pools usually have in order to keep the water clean are: drains, a water filter, a basin, returns, a pump, PVC plastic plumbing, and a chemical feeder.
Besides this, it is also interesting to know that there are several different basic types of swimming pools. One of these main types of swimming pools is the vinyl lined in-ground one. Vinyl lined in-ground swimming pools can usually be built faster than many others and are one of the cheapest options, although they might not endure as much as others.
Despite of this, the cheapest option nowadays available for constructing a swimming pool is an above the ground one. Above-ground swimming pools are the easiest to build since they are usually bought as pre-fabricated kits, in such a way that often can be installed by a non professional. But, in order to avoid wasting time or money by doing something incorrectly, it is always recommended to hire a professional to do the job.
Fiberglas pools, other of the most usual basic types of swimming pools in the market, are more complicated to construct but are created specifically according to the needs and space of the client. These swimming pools are made by installing fiberglass reinforced plastic in a ground hole, both of them specifically shaped as the client might desire.
Gunite and poured concrete swimming pools are some of the most popular options. Gunite pools are made by spraying a mixture of sand and cement in a hole which has been carefully prepared for the pool. Poured concrete swimming pools are similar, but their construction usually is much more difficult.

Say goodbye to swimming pool water problems – with regular use of swimming pool chemicals
By: Ukpoolstore | Posted: 17th April 2009
If you are a pool owner or looking after the maintenance of a swimming pool, you may often face issues regarding your pool water. Maintaining a swimming pool isn’t a hard task, but you need to follow the correct guidelines and know how to deal with pool water problems, especially the correct usage of pool chemicals and swimming pool sanitizers.
Stabilized chlorine granules are ideal pool chemicals which you could use daily in your swimming pool. These chlorine granules have the capacity to destroy harmful bacteria. They do not affect the pH level of the pool water as they already contain clarifiers as well as oxidizers, so it would be a recommended to use them.
You may find that you have algae issues in your swimming pool. It could be either green algae, yellow algae or even harder to remove black algae. You will need to act fast in order to get rid of it. Whenever you opt for an algicide, make sure that you check for the period of effectiveness. Some algicide products promise an algae free pool for almost 6 months after its application; however some products can cause discolouration, adding a haze which gives an untidy look to your swimming pool.
While cleaning your swimming pool, you may have noticed some marks above your water lines which are hard to erase. You can always buy a waterline cleaning gel which is specially formulated for this purpose. The waterline cleaning gel has low foaming properties with non abrasive properties which works wonders on removing the tide marks.
As you try different methods of maintaining your swimming pool, you will come across many varieties of pool chemicals, water clarifiers and algicides which will promise to solve your pool water issues. You should always research their composition, directions for use as well as the dosage required when choosing the right product.
Maintaining swimming pools involves routine treatment and the appropriate use of pool chemicals and swimming pool sanitizers. The most common problems with swimming pools relate to the pool water and its chemistry. Common issues are those regarding swimming pool algae, staining of the pool, chlorine smell and cloudy pool water to name but a few.
While maintaining swimming pool water, you will mainly have to deal with three types of pool algae which are free floating green algae, yellow or mustard algae and finally, black algae. You should therefore use the right kind of swimming pool water clarifiers & algicides such as polyaluminium chloride (PAC) which is a liquid based coagulant. It is advised to also check for the correct dosing system, a FlocPac super clarifier, ground aluminium sulphate or even an Algaecide which contains benzalkonium chloride. It is important that you follow the directions for use in accordance with the quantity usage for best results.
Swimming pool chemicals include swimming pool sanitizers such as stabilized chlorine granules, HTH dedusted granules, aquabrome, sodium hypochlorite (Used on CWS Tank cleaning) or calcium hypochlorite which are easily available and thoroughly sanitize the swimming pool water. While the HTH Calcium hypochlorite can be used in soft water as well as hard water, not only does it act as a sanitizer, it adds much needed calcium into the swimming pool water.
When your swimming pool is being cleaned, you should ensure the right pH level of the water and it should range between 7.4 - 7.6. You can always opt for swimming pool chemicals (in granule form) which work well towards balancing the pH level, be it increasing the pH level or decreasing the pH level.
A Swimming Pool is a place where you can enjoy yourself and relax. So make sure the swimming pool has a regular sanitizing and cleaning schedule which makes the pool water ideal to be used without facing any health risks or hazards.

What is an ideal swimming pool temperature? This is a difficult question to answer because it varies based on individual swimmers preferences. Based on recommended heater temperatures and settings from virtually all manufactures, the ideal range for both indoor swimming pools and outdoor swimming pools is anywhere from 75 degrees to 85 degrees Fahrenheit. This figure should not be thought of as final as temperature and comfort does differ from person to person and environment to environment, but it a good goal to reach.
If you have a backyard swimming pool without a heater, looking for an ideal temperature is a difficult task. The temperature of the swimming pool will gradually increase as the season changes and as the pool heats up, but the initial temperature of your swimming pool in the early parts of the swimming season will be quite cold – usually well less than 70 degrees Fahrenheit. Even though there is no proper pool temperature, swimming pools less than 65 degrees Fahrenheit are unpleasant even for the most adventurous swimmers. On the other side, if you do have an outdoor swimming pool with a heater, set it at something that is comfortable to your swimmers and your activity level. For instance, cooler pool water is more ideal for exercising where warmer water is better for a lounge / beach atmosphere. But, keep in mind that turning up your heater too much can lead to unexpected drama.
When you increase the temperature of your swimming pool water, it can have an effect on pool maintenance. With higher temperature comes more water evaporation. This means you will need to be more diligent about filling up your swimming pool to keep the water in your skimmers. Higher water temperatures also mean a faster buildup of dissolved solids. This is basically the “bad stuff” that the chlorine attacks in swimming pool water. Higher pool water temperatures will also burn off your chlorine and pool sanitizing agents much more quickly. Algae also love the hot water so they will grow faster and force more serious and diligent swimming pool vacuuming, brushing, and cleanup.
Even if you don’t have a swimming pool heater to maintain your swimming pools temperature, the same concerns of a warmer pool will eventually plague your pool in peak summer heat environments. Keep an eye out for seasonal changes and how they will affect your water chemistry. The most important reading in your swimming pool during hot and cold times will be your total alkalinity. When the weather is cooler, your total alkalinity should be increased. In warmer weather, your total alkalinity should be decreased with a muriatic acid to keep the saturation index fairly constant.
There is no ideal swimming pool temperature but you should adjust your temperature based on your individual preference. Also, keep in mind the added responsibilities that come with maintaining a warmer pool. Watch out for seasonal changes and note how they affect your swimming pool chemistry. Both cold and warm temperatures have an effect on pool chemistry and maintenance routines.

Replacing the inside door handle on a Toyota Corolla can be done by removing one screw. Once you have the screw removed you will need to release the clip that holds the linkage to the door handle and then replace it in reverse order. The inside door handle seldom cracks, but it can happen making your Toyota Corolla unsightly.
New Toyota Corolla inside door handles are fairly inexpensive if you buy one from someone other than the dealer. After market inside door handles can be bought for less than ten dollars and they are good enough quality that you would never know that they were after market unless you studied them up close. A few quick searches ought to yield you several places to choose from to buy an inside door handle.
Tapping a hole is easy, but it requires the right tools.
First you should know what size screw or bolt you intent to put in the hole that you are about to tap and select the drill and tap accordingly.
You will need to know four things before you begin:
1) The size of the screw or bolt you intent to put into the hole you are about to tap.
2) The amount of threads per inch on the screw or bolt you intent to use in the newly threaded hole.
3) Tap drill size
4) Tap size.
Once you have the screw or bolt you intend to use you will need to plug the size and thread count into the following formula to determine the tap drill size you will need to use.
TD = MD - (1/N) where TD is the tap drill size, MD is the major diameter of the tap (e.g., 3/8 inch for a 3/8"-16 tap), and N is the number of threads per inch (16 in the case of a 3/8"-16 tap). For a 3/8"-16 tap, the above formula would produce 5/16 as a result, which is the correct tap drill diameter for a 3/8"-16 tap. The result produces a tap drill size that leaves enough material in the wall of the hole to result in an approximate 75 percent thread that will provide a strong anchor point for you to secure your fastener to.
The type of tap that you use is as important in determining as the correct size. There are different materials that you can tap a threaded hole into and each one will require a different type of tap. Also, the type of hole you are threading determines a specific tap as well.
Hole Types:
A Through Hole-A hole to be tapped that goes entirely through the material is called a “through hole.” A through hole can be tapped by using a tapered tap to cut the threads. Once the tap is run in and out of the hole the threads would be ready for use.
A Blind Hole-A hole that goes into a piece of material and does not go all the way through is called a “blind hole.” When tapping a blind hole you will need to determine if what you are screwing into the hole will go all the way to the bottom or not. If you want it to go all the way to the bottom you will need to use three taps. If threads are to be cut to the bottom of a blind hole, the taper tap will be followed by an intermediate, or plug tap, and then a bottoming tap to finish the operation.
First use a tapered tap to go in as far as it can then use a plug tap to continue the threads and then finally a bottoming tap to finish the threads all the way to the bottom of the hole.
When you are using a tap you need to lubricate the tap and hole to prevent the tap from getting hot and sticking that will break the tap.
There are two types of lubricant for a tap, one is like a wax and the other is tap oil.
It is not a good idea to use the wax type of lubricant on a blind hole because the wax will hold the particles that result from tapping and may cause the tap to bind inside the hole resulting in a broken tap. It is better to use the tap oil because it will allow the tap filings to run out of the hole and not get bound up in the tap.
Taps and dies are cutting tools used to create screw threads in solid substances including, but not limited to, metal, wood, and plastic. A tap is used to cut the female portion of the mating pair (e.g. a nut). A die is used to cut the male portion of the mating pair (e.g. a bolt). The process of cutting the threads in a hole is called "tapping" the hole. The process of cutting with a die is called "threading" (or sometimes "chasing", although "chasing" as a technical term can have restricted meanings).
