In one sentence, describe what the following article is about: Water heaters will usually last somewhere between 8 to 15 years. If your water heater has stopped working, there's a good chance that it will need to be replaced. If you notice water dripping from the bottom of your tank or sitting in a rusty pool beneath it, this means that the steel tank has rusted through. This kind of damage is not fixable and the tank will need to be replaced. However, if you are experiencing problems such as insufficient or no hot water, your heater may just need to be fixed rather than replaced. If you're unsure what the problem is, call a professional plumber. Plumbing codes vary by region, so it's a good idea to call your local plumbing inspector to find out the specific requirements for your area and whether you need to get a permit before replacing your heater. It is also a good idea to provide a description of the new water heater and the materials you intend to use while installing it. The plumbing inspector may have some useful feedback or advice that will help you with your installation. If this is your first time replacing a water heater and you are concerned with safety, you can request for a local plumbing or electrical inspector to check your work. Replacing a water heater requires quite a number of tools and materials. You can save yourself time and frustration if you have all of the necessary items lined up and ready to go before you begin. Although the exact items will vary according to the type of water heater, the following guide should help: Tools: screwdriver, adjustable wrench, pipe wrench, tube cutter, wire stripper/cutter electrical tape, plumbers tape, carpenter's level, tape measure, rags and safety glasses. Materials: new gas (or electric) water heater, water and gas piping, fittings, solder, pressure relief valve, discharge pipe, pipe thread compound, venting pipe and connectors.
Summary: Know when your water heater needs to be replaced. Call your local plumbing inspector. Gather your tools and materials.

In one sentence, describe what the following article is about: Whenever you make a request or you need to ask for something, start by saying "please." That way, it doesn't sound like you're demanding the other person to do things for you. Once someone completes the task that you asked them to do, respond by saying "thank you" so the other person knows you're grateful for what they just did. For example, you may say, "Can you please hand me that book?" Once they hand you the book, say, "Thank you." Say "thank you" whenever someone helps you in a small way, such as a person ringing you up at a store or a person taking your order at a restaurant. If someone says "thank you" to you, respond with "you're welcome" to stay polite. If you're getting together with someone and you haven't met before, introduce yourself by name and ask them what their name is. When they say their name, repeat it so you have a better chance at remembering it later on. Offer your hand for a handshake and use a firm grip, but not so firm that you hurt the other person. For example, you can say, "Hi, my name is James. What's yours?" Different cultures and countries have different manners when it comes to introductions, so make sure you're familiar with the etiquette where you are. If you're with another person and you run into somebody you know, be sure to introduce them to one another if they haven't met before. For example, you may say, "Hi John, this is Melissa. Melissa, this is John." to other people without interrupting them. When another person starts talking, make eye contact with them and pay attention to what they're saying so you can carry on the conversation. Avoid trying to talk over them or cutting them off since you'll come across as rude. Once the person is done speaking, respond to what they just said so they know you were listening to what they were telling you. If you and another person start talking at the same time, stop and ask them to continue to show that you care about what they have to say. Inappropriate language can come across as rude, especially when you use it in public conversation. Do your best to try and eliminate curse words from your vocabulary while you're talking with other people. Rather than saying the word, try to find a replacement or just pause during your conversation to recollect your thoughts and plan out what you're going to say. For example, you may use the words "dang" or "darn" in place of harsher curse words. You may also find more descriptive adjectives in place of bad words. For example, instead of saying something is "f***ing great," you may say it was "amazing" instead.
Summary: Use "please" and "thank you" when you're asking for something. Introduce yourself by name when you meet someone for the first time. Listen Avoid using bad language.

In one sentence, describe what the following article is about: If you need something ground into a paste or powder, this is the ideal tool. Items that are good to grind or crush in the mortar and pestle include peppercorns, spice seeds, herb seeds, fresh herb and spice leaves, rice, nuts, other plant seeds, hard candies, sea salt, and so on. Anything used for baking or eating that can be crushed is likely to work in the mortar and pestle. If you need something chopped, pureed, or blended, you may be better off with another tool, such as a blender or processor. The recipe will often be a guide on this. Measure out your whole peppercorns, cinnamon, or other ingredient and place it in the mortar. Fill the mortar no more than full with raw spices; otherwise, it will be difficult to get an even grind. If you have too much to fit, it's fine to process the spices in batches. Hold the mortar in place with one hand, take the pestle in your opposite fist, and twist it against the ingredients in the mortar so that they are ground against its bottom and sides. Evenly grind, bash or crush all of the spices, using the pestle to mix and grind them until they are all reduced to the same consistency. Continue until the ingredients are as coarse or fine as you want. See below to learn specific techniques for grinding, crushing or bashing your ingredients. Each technique will result in a different consistency, and can affect the flavor and final outcome of your dish. You can either place the freshly ground contents of the mortar into a glass spice jar with a tight-fitting lid, or go ahead and measure out how much you need for your recipe.
Summary:
Read the recipe for processing instructions. Place the raw ingredients in the mortar. Use the pestle to process to your desired consistency. Store or measure out the ingredients.
