In the world of plumbing every engineer is aware of the dreadful water hammer, and what measures must be taken to prevent. Water hammer have been around since the first pipeline systems were built. For thousands of years mankind has been looking for a solution, and in this day and age, more than one method has been found.
The study of water hammer was technically started in the year 1883 through the work of German physiologist Johannes von Kries. Although the first accountable detailing of the subject is extended as far back as before the Common Era through a Roman named Marcus Vitruvius Pollio, who was describing the effect on the Roman public water supply system. Since then many have taken up the task to find an equation correlating to water hammers. In 1898, a Russian fluid dynamicist named Nikolay Yegorovich Zhukovsky derived an equation from the work of Johannes von Kries. This method known as the “Joukowsky equation” is still frequently used by civil engineers today.
Water hammer are commonly found in areas where the momentum of a fluid or gas is suddenly shifted or stopped, causing a pressure surge to occur within the piping system with no exit point. Without a point in which to exit the system, this surge of pressure can cause extensive problems. Typical water hammer complications exhibit loud banging noises, which is where the term water hammer is believed to be obtained from. However, in some cases these noises are accompanied by vibrations and pipe collapses, which can be detrimental to any system. Due to the high pressure outputs of most plumbing systems, precautionary measures must be taken to ensure the safety of the system from water hammers.
Luckily, there are a few ways to deal with this dilemma for the average home owner, do-it-yourselfer, and plumber. Water hammer arrestors and permanent air chambers are the ideal way to control water hammers in your home. Water hammer arrestors work through an innovative structure in which the piston compresses the air going through the pipeline, leaving the momentum of the water flow at a standstill, and the plumbing system safe. Air chambers are capped pipes designed to help reduce the water hammer noise, thus eliminating any further issues. They are usually built through a tee type connection with a 12’’- 24’’ pipe leading out from the pipeline, with a cap at the top.
Today almost every household contains either a water hammer arrestor, or a permanent air chamber to help deflect the effects of water hammers. Their destructiveness can be crucial if the proper precautions are not taking to control them. Water hammers can occur in any household, and are usually common in homes with washing machines, dishwashers, and any other appliance that shuts off water flow promptly. These incidents will continue to happen until they are handled properly. Water hammers have been around for millenniums, and there is finally a way to avoid them, so don’t wait for that dreadful noise to apply the precautionary appliances needed, get them now and save the headache of dealing with it later.

It always seems to happen during Thanksgiving dinner, or while entertaining a dozen friends. You’re in the kitchen chatting. You scrape a few potato peels into the sink. Then you flip on the garbage disposal. A horrendous noise cuts all conversation short–it’s as if Godzilla has arrived, chewing on iron filings.
We’ve all experienced it. You likely turned the unit off intending to deal with it the next day. The good news is that the sounds your floundering garbage disposal makes give clues to precisely what’s wrong with the unit. Here’s how to interpret those noises along with some guidelines on fixes.
Clanking, Rattling, Grinding
Godzilla isn’t chewing on iron filings in your disposal, but it’s likely that something glass, metallic, or otherwise non-grindable is getting battered by the impellers. (Tip: Check for your wedding ring!) Whatever it is, it’ll need to be removed before using the unit again or you’ll risk further damage. The first step in all appliance and plumbing repair is to unplug the unit. Just to be sure, consider cutting off power at the fuse box as well. A flashlight and some narrow tongs may be all you need to remove the object–sort of like the kid’s game Operation, without the electric shocks.
You’ve used one, probably countless times. And while you certainly know that it controls the temperature of an interior space, do you really know what a thermostat does? A mechanical and a programmable thermostat have similar goals – to keep your homecomfortable. It’s how they go about it that’s really interesting.
Thermostats Maintain the Temperature
While all thermostats show some measurement or gauge of temperature, whether manually or digitally, that’s only part of the job. Their primary function is to regulate the heating or cooling to a temperature setting that you choose.
To accomplish a relatively constant temperature, they have to communicate with the HVAC unit. When the temperature gets too high, the thermostat either tells the unit to switch on the cooling feature in summer or to switch off the heat in winter. When it drops too low, the same happens in reverse. You can also adjust a thermostat to control how soon it switches on.
Mechanical thermostats adjust with dials or levers to control the temperature.
