  • Typically, I find that a lot of plumbing apprentices and even some skilled foremen have a hard time understanding venting. I have also noticed that new plumbing system designers will either do one of thee things: 1. They will under-vent a drainage system. 2. They will add illegal flat vents below the flood level rim of fixtures, (especially floor drains and floor sinks in commercial kitchens and mechanical rooms). or 3. They will over-vent a drainage system by venting every single fixture. For example, in a row of 8 water closets I have seen a vent placed on every single water closet. This is not only unnecessary, because it does not enhance system performance, but it is also more expensive to install. Instead of venting every single water closet, why not use a circuit vent? Don’t understand circuit venting?… This book explains it in awesome detail.
    Bob Scott has done an excellent job of explaining plumbing venting in this book. He uses many isometric drawings to clearly show how each type of vent system works. He also uses pictures taken from actual job sites to show common mistakes, and the correct field installations. His descriptions and wording are clear and concise. You will have a much better understanding of venting after you study this book.
    Bottom line: If you are a plumber, plumbing designer, plans inspector, or building inspector, I would strongly recommend that you purchase this book. This is also an excellent companion to the ICC Plumbing Code Commentary. Knowledge of the craft is what separates your average plumber from a valuable and quality tradesmen. Don’t hesitate, buy this book!
  • As fun as planning to do your own plumbing can seem, it is a very important reason to start learning how now. Another thing is that it can save you a lot of money in the future, so you can handle any issues yourself. These tips below can help you start.When it gets very cold, your pipes may freeze. If it does, relieve the pressure in the pipe by turning on the tap so the water can be released as the pipe thaws. This relieves the pressure contained in the pipe as it also prevents it from bursting, which would reduce the damage done to your house.Group all of your plumbing repairs before scheduling a plumber to come out. Check all of your fixtures and faucets. If anything is dripping, running or clogged, make a list for the plumber. That way, when the plumber comes, they can do all of the jobs in one visit. This will cut down on charges.If you have a clogged drain, don’t use cleaning chemicals to try to clear the clog. These harsh chemicals can corrode your metal pipes leading to leaks and broken pipes over time. Instead, stick to a plunger or make use of a plumbing snake to clear them.Take preventative measures to keep your plumbing costs low. Clogs are the most commonly reported problems when it comes to plumbing issues. Clogs in drains can be caused by hair, among other things. Stop hair from going down drains with a drain cover or screen designed for this purpose. It’s a lot simpler to eliminate hair that is on a screen than eliminating it off a pipe.One way to avoid a common plumbing problem is to make sure never to flush anything but human waste and toilet paper down a toilet. Other things made of paper like tissues, paper towels, and the like do not dissolve the same way toilet paper does and can get stuck.When plunging a drain to attempt to remove a blockage, first make sure that the drain is completely covered in water. This helps to form a seal. Then, plunge at least fifteen to twenty times before stopping. Repeat the process two to three times. If this doesn’t work, try a chemical drain cleaner.If you find that your pipes have frozen during the cold winter months open all the faucets in your home. This lowers the water pressure for when the pipes thaw and the water is freely flowing again. Make sure to open all the faucets not just those that are frequently used.Always keep a trash bin in the bathroom so that you can dispose of cotton swabs, facial pads, and hair. Do not put these materials in the toilet as they can cause clogs over time and disrupt your water flow. These items will not dissolve or break down when submerged in water.If you are the kind of person who travels a great deal, then remember that different countries may have very different kinds of plumbing systems available. If you are not sure of how things work in the region where you experience problems, then you should either do research or avoid fixing the problem yourself.If you have an ice maker or other plumbing going to your refrigerator, every six months or so pull the refrigerator away from the wall and inspect this plumbing. There should be no condensation or corrosion on these plumbing lines, if there is, contact a plumber and have them look at it.Avoid flushing cotton balls, cotton swabs and any feminine sanitary products down the toilet. Even small panty liners can cause big problems because their adhesive backing can stick to pipes and cause stoppages. Keep a small, covered wastebasket next to the toilet to encourage guests to properly dispose of used sanitary articles.Run dishwashers and washing machines at night, or during times when people are not using that much water. This will keep water pressure strong for showers and other things, while making sure that dishwashing and laundry still takes place in a timely manner. It also preserves energy costs and use.Never flush menstrual products, such as pads or tampons, even if the box says it’s okay. These products can cause major clogs in your plumbing that cannot be removed with a simple plunger. Ensure that all women in your household understand the importance of placing these items in an appropriate receptacle.Avoid over-tightening water faucet handles. Use only enough pressure to stop the water from flowing and dripping from the faucet. Anything else is overkill and will quickly wear out the gaskets and washers inside those handles and cause leaking or the inability to stop the water from coming out of the faucet.While planning to do your own plumbing was incredibly interesting. You should feel better you know how to do it correctly and safely. You can now apply your newly acquired plumbing skills and knowledge either to maintain your plumbing, trying to repair it, or bettering your own home system.
