Drywalls are paels used to create interior walls as well as for creating ceilings. Drywalls offer a much quicker and easy alternative to having brick walls on the interior of the house. With the incorporation of drywall the a home can be built much quicker than in the past. For this reason drywalls have become very popular over the years. Drywalls need however to be fastened to a wooden frame and the best way to fasten them is by using drywall screws.
Drywall screws are special screws which have been made specifically for the drywall application. Drywalls are made of plaster and paper Armaturen
. The plaster used is called plaster of Paris or gypsum plaster. Plaster is like cement in that it is also mixed with water to form a paste, but it is a much softer substance and can be easily cut. In order to make the drywall the plaster is placed in between two sheets of hard paper. This is then compressed and the panel is complete. The drywall panels are very sturdy and are perfect for interior walls as they are do not come into contact with any of the elements. Drywall however is prone to become mouldy if it comes into contact with water, which usually occurs when there is a leakage of some sort in the house.
Drywall screws have a very sharp point making it easier to puncture the drywall. You will find screws which have two variants. The differences in the drywall screws depends on the type of frame it is being attached to. A screw which is being attached to a wooden frame has a thread which has wider spacing. A drywall screw which is being attached to a metal frame is a screw which is larger and also a much narrower thread spacing. This type of drywall screw is called a fine screw. The tighter thread allows the drill to more easily move through the metal, while a softer substance such as plaster and paper does not require much to be penetrated. This type of drywall screw is called a course drywall screw. Purchasing canisters with filters for removing chemicals, volatile compounds, odors, bad taste, etc. from the tap water coming into your home can be a confusing proposition. Obviously cost, type of filtration, and ease of installation, are factors that should be considered before purchasing. Many manufacturers with various brands exist in today’s market, and each type of canister/filter may have special instructions for installation. How you install your new filtration device will depend on whether you want a over the counter, or under the counter filter system. Supplemental information may be helpful when doing it yourself.
The majority of over the counter filters are fairly simple, and installation may only take a few minutes of your time, and the use of a few common tools such a screw drivers, regular or channel lock pliers, and Teflon tape. Most sink faucets come with an aerator device screwed on the end of the faucet. To remove simply turn the aerator counter clockwise to remove. If it is screwed on too tight to remove by hand, use a pair of pliers mentioned above. If you want to keep the aerator for future use, you may want to wrap the aerator with a piece of old cloth and a few rounds of duct tape to prevent scratching the chrome. Once removed, the hose end connector that leads to the filter device simply screws back onto the faucet. Teflon tape can be purchased at most hardware stores, and is used to prevent water from leaking between the connections. Some filtration devices come with this tape included. Wrap the Teflon tape clockwise two or three times around the thread keeping it flat and tight if possible to prevent it from bunching up an causing a problem with threading the new connector onto the faucet. Now, thread the new connector onto the faucet turning it clockwise. With the Teflon tape, usually hand tight is sufficient, or you can use the tip mentioned above to prevent scratching the chrome connector if using pliers to tighten. Most of these connectors have a diverter that simply pulls out to force the water into the canister and through the filter. Pour a glass of water and taste the difference.
Under the counter filters are a little more difficult and may take 30 minutes to an hour to install with the use of some special tools. These devices may require a plumber or handyman to install, but if you want to attempt to do it yourself, here are a few how to instructions along with a few considerations for you. Although most of the filter devices sold come with instructions, many are vague and may or may not give enough information depending on the type of plumbing under your sink. First be sure to turn off the water supply coming into your house. Open the faucet at your sink and maybe your outside hydrant to remove water pressure. Under the sink you will usually find a shut off device for hot and cold water that connects to plastic or copper lines leading to your sink faucet. After shutting off the cold water supply line, remove the supply line connector in the same manner mentioned above for over the counter connectors. Most filter canisters come with connectors, tape, O-rings, hoses, etc., needed for the installation. They will come with a dispenser faucet which attaches to your sink and will be separate from your regular faucet. Even before buying an under the counter dispenser, be sure that your sink has a special “knock out” hole which can be seen from under the sink.
