There were days when concrete, ceramic and metal were the only materials used for residential plumbing tubing and piping. Even though many metals such as galvanized steel and copper are still used today, metal plumbing does require some laborious installation. Generally, pipes need to be welded or threaded and the tubing most often than not requires the installation of sensitive compression mobile home plumbing fittings. Plastic pipes have over the years given plumbers an option that’s not only easier to install but also avoids some plumbing problems common with metal pipes. Some of the plastics commonly used include PEX (Cross Linked Polyethylene), CPVC (Chlorinated Polyvinyl Chloride), HDPE (High Density Polyethylene) and PVC (Polyvinyl Chloride). It is important to note that both metal and plastic piping have their place in residentialbathroom plumbing installations.
Plastic piping is generally more corrosion resistant since it is not easily corroded by exposure to common household chemicals and water. As a matter of fact, plastic formulas can be adjusted to allow them to stand up to the demands of various plumbing needs such as drainage and water supply. Also, unlike metal, plastic doesn’t conduct heat as well so it can easily maintain the temperature of the water. Whereas copper pipes require some form of insulation to prevent dripping and sweating, PVC pipes can easily stay dry without any insulation. This becomes extremely helpful with condensate drains for boilers, air conditioners and other appliances.
Plastics are also non-reactive, as any experienced plumber will tell you, connecting dissimilar metals such as iron and copper has been known to cause corrosion. On the other hand, plastic pipes can be connected with metal pipes or with each other without the risk of any damaging chemical reaction. Some plumbers also claim that plastic drainpipes are less likely to clog and easier to unclog as well than metal pipes.
There are certain reasons though why plastics are not always the ideal choice. Even though they don’t transfer heat as well, plastics do contract and expand depending on the temperature of the surrounding air as well as the fluid inside them. Plastics also burn and melt at lower temperatures than most metals and can emit some toxic fumes in the process. This does present an additional danger in the event of a house fire. Due to this, most building codes tend to place more safety restrictions on plastic pipes than they do on metal pipes. There are also certain plastic pipes such as PVC which are quite sensitive to sunlight and may become brittle when exposed to UV rays. For such pipes to be used outdoors, it is always recommended that latex painting or some other protective coating be applied on them so as make them last longer.
Whether you opt for plastic or metal plumbing, it is important to note that both plumbing pipes typically require some type of support to help the pipes carry the weight of the fluids passing through them and to also minimize instances of vibration. Without proper support, pipes may shift out of place or even sag. Interestingly, narrow pipes and tubing tend to require more support than those large-diameter tubes. The rule of thumb though is to have supports placed at four foot intervals for horizontal pipes. Some of the most common ways of supporting pipes include the use of clamps, anchors and strapping.
Even though the advent of plastic plumbing has significantly reduced the amount of labor required to install pipes, it has significantly increased the amount of knowledge demanded so as to design a functional plumbing system. In this regard, here are some of the popular mobile home plumbing fittings readily available in the market.
Product Details: constructed of durable POM (Polyoxymethylene), this is a quick connect compression fitting for gray and Pex plumbing. The unit is easy to install since no cement or tools are needed, the fittings push against the OD and ID of the pipe, creating a strong and long term seal.
