Reducing the amount of air that leaks in and out of your home is a cost-effective way to cut heating and cooling costs, improve durability, increase comfort, and create a healthier indoor environment. Caulking and weatherstripping are two simple and effective air-sealing techniques that offer quick returns on investment, often one year or less. Caulk is generally used for cracks and openings between stationary house components such as around door and window frames, and weatherstripping is used to seal components that move, such as doors and operable windows.

Extreme cold temperatures can have adverse effects on your wire and cable, causing them to temporarily become brittle and inflexible. In these conditions, some cables will stiffen and even crack if they are installed below recommended temperatures.
The most effective drill bits for plastics are spur-point bits, also known as dowel bits. They are specifically angled to make smooth cuts in the material. A spur-point bit has a central point and spurs that keep the bit aligned, maintaining a clean, neat hole. Some soft materials, including plastics, benefit from countersinking before actually drilling. A power drill is used to countersink or create a depression in the material first. Using a countersink bit along with a plastic drill bit ensures that the drill bit remains in the center of the depression. Never use twist bits when drilling plastics; they can splinter and ruin the material.
Overtightening supply tubes, pipe and fittings and toilet bolts is one of the most frequent mistakes DIYers make. If you crank too hard on a galvanized or black pipe, coupling, tee or elbow, you risk cracking the fitting. The crack may not happen right away, but the excessive force can break the fitting weeks later, causing a flood.
Assume you need four wires to power your connection. Running each wire individually would be the old-fashioned way, but now, manufacturers surround all four wires with a polyvinyl chloride (PVC) or rubber jacket for protection and ease of installation. These two options, rubber and PVC, have different benefits, making them appropriate for varying situations. Knowing the difference between these two outer layers can help you better select the right cable for your work.
DescriptionDanley PaveX Crack-A-Joint induces a controlled crack to the full depth of the concrete. The PVC strip is simply inserted into wet concrete flush with the finished surface. The Rip-a-strip capping eliminates the need for tooled or sawn joints and protects the joint from ingress from foreign particles. Once the pavement has set, the Rip-a-strip capping can be peeled off leaving a clean, joint line.
Corrosion Free Joint
Eliminates the need for tooled or sawn joins
Easy to install
No need to return the next day for saw cutting
Reduces the risk of early shrinkage cracking
Smooth transition over joint
Stress cracks more often occur in large windows that are beneath overhangs or are recessed behind a protruding outward room. The shadow lines created by the overhang or wall set up a quickly changing stress factor from the glass that is in the sunny, hot area that contrasts with the glass in the cool, shaded area.
If the wind blows down a large shade tree in your yard or a new house goes up next door, it could change the amount of shade on your window and create conditions for thermal stress cracks. Seasonal factors, like dramatic overnight temperature changes, are a common cause of stress cracks as well.
The short answer is: not really. Stress cracks are a naturally occurring result of expanding and contracting glass due to temperature changes. However, installing thicker glass and choosing glass features based on your climate and sun exposure needs may help decrease your risk.
If you have Pella Windows in your home and discover a stress crack, connect with your local Pella representative for assistance in replacement of the glass and/or the window as needed. Or call the Pella customer service team at 1-800-374-4758 or visit -to-buy/default.aspx to find a Pella representative near you.
This family are thermoplastic alloys formed by the addition of compatible modifying agents to PVC. The modifying agents improve toughness, impact properties and resistance to crack growth that improves the fracture toughness and ductility of the material. This enhanced toughness enables modified PVC pipes to be manufactured with a thinner wall, with subsequent material savings and improved hydraulic properties. The alloying of PVC with modifying polymers achieves improvement in resistance to cracking. The result is the minimisation of the effect of stress concentrators such as scratches.
As the years go by, your drain pipe may become damaged due to corrosion, leaks, separations, or other factors. This can be caused by the drain trap no longer being able to hold water, or the drain pipe itself may be cracked or otherwise damaged. While many homeowners believe that using an electric power snake is the best way to clear a blocked drain, this can actually cause further damage to the pipe. An alternative in some cases is to clean the clogs by removing them via a water jet, drain bladder, or pressure. Naturally, once a drain pipe is completely damaged it will need to have a replacement as soon as possible.
Tree root intrusion is another common cause of damage to drain pipes. Tree roots can grow into your sewer pipe and crack or block the pipe. This can lead to sewage back up in your home and significant damage to your pipe. To avoid this, it is important to have your pipe regularly inspected for tree roots. You may feel tempted to cut, rip, or blow out root blockages, however, this can actually cause more damage to your pipe. An alternative is to use chemical treatments, which will kill the roots without damaging your pipe. However, it is best to use these treatments before the roots have a chance to cause significant damage and blockage.
Your home has many pipes and fixtures. Some of these are visible, such as the ones in your kitchen and bathroom, but many are hidden behind your walls. When there are issues with your drain pipes, your first thought is to have the issue resolved as quickly as possible. However, sometimes quick actions can result in more damage than good. So what should you avoid doing when you think you have a cracked or damaged drain pipe?
There are several things that you can do in order to avoid damage to your PVC drain pipes, such as avoiding using electric power snakes, cable augers, or other devices that can cause physical damage. PVC drain piping can be damaged by constant scraping from these devices. If you do use electric power snakes, cable augers, or other such devices, it is important to make sure that the tip is not in direct contact with the pipe as this can cause significant damage.
Porcelain plumbing fixtures can also be damaged if you are not careful. Electric sewer cleaning blades can cause chips and cracks in your porcelain fixtures. There are methods to insert the blades into a sink, tub, or toilet without causing damage. In some cases, it is still possible to cause chips and cracks, but the risk can of doing so can be lowered. Being careful when using these devices near porcelain fixtures is a basic 1st step.
Another way to avoid a cracked or damaged drain pipe is to have your pipe regularly inspected. A professional will be able to identify any potential problems and fix them before they cause serious damage. This is especially important if you have an older home, as the pipes are more likely to be made of materials that are no longer used in modern construction. Finally, be careful when using any devices that could potentially damage your drain pipe. This includes high-pressure water jets and electric sewer cleaning blades. If you are not careful, you could cause serious damage that will require extensive repairs.
The pipe was excavated and later examined in the laboratory. The pipe showed indications of rapid crack propagation that would be consistent with a high-pressure event. The crack origin was located a few inches outside of the bell and spigot connection. The fracture surface at the origin was discolored or stained in an elliptical pattern that extended over a length of approximately 5 inches. The difference in color and texture (fracture topology) suggests that this may have been a pre-existing crack that developed over prior to the leak and rupture incidents. At some point, the crack became unstable and grew suddenly and catastrophically, leading to the large-scale rupture.
In order to understand the effect of the pre-existing crack on the remaining strength of the pipe, a fracture mechanics analysis was performed. The analysis found that, at a pressure of 180 psi and a temperature of 26F, the pipe would fail catastrophically. Moreover, with the 5-inch long elliptical through-wall crack in the subject pipe, brittle fracture was imminent. The cold temperature also reduced the fracture toughness of the material significantly.
Normally, a through-wall crack would have allowed water to leak out of the pipe in a relatively benign manner. In fact, plastic pipes are generally designed such that they can tolerate the presence of small cracks without rupturing. However, the combination of a relatively long crack and elevated pressure led to a situation in which catastrophic rupture was imminent. The exposure to cold air on the night of the incident further precipitated the rupture.
Water expands when frozen and can pressure already-brittle piping and joints. The constant freezing and thawing action can buckle pipes, cracking and fracturing them and creating a series of leaks in your system. A way to counteract this problem is using thicker pipes.
Many homeowners are drawn to the glossy, modern look of vinyl fencing, as it is the convenient, low-maintenance alternative to traditional wooden fencing. Not only is it extremely weather resistant, it won't ever rot, splinter, warp or crack. It's also insect-proof and never needs to be painted, scraped or sanded. One of the only downsides is that it tends to show dirt and stains somewhat quickly (particularly on white vinyl fencing). 2ff7e9595c
