If you have had 1 leak, more will genuinely ensue - you can do something about it before further damage is done and further money is wasted.
Circulating hot water is the fastest way to wear out your pipes. In fact 90% of all pinhole leaks and slab leaks happen in hot water lines for the following reasons:

2. Chemicals in water when heated are even more corrosive
3. Chemicals in water when heated and circulated straight through copper pipes that bend colse to corners and turn up walls and curve colse to electrical conduit and sewer pipes and are reduced in size as water passes straight through a construction is extremely corrosive
In order to understand the clarification it is helpful to know what causes the problem. With a microscopic comprehension into how domestic hot water recirculation lines or recirc loops are built and how they work we can see that the rejoinder is as easy as flipping a switch.
Apartments, hotels and larger homes have recirc loops designed to move hot water to the farthest fixture from the boiler or water heater in a inexpensive estimate of time. Each loop has a pump pushing water straight through a copper pipe 24 hours a day, 7 days a week. Each loop has multiple joints and fittings that obstruct the flow of water. Gate or ball valves and flapper checks and expansion tanks and anyone else the plumber had on his truck the day he built the line generate disturbances in the flow path.
Water likes to flow in a nice level line with no obstructions. This is called laminar flow - nice and smooth. anyone in the flow path can disrupt the flow and cause an eddy to form. Eddies are the bad boys, the unwanted visitor, the black sheep of the family.
Create a microscopic friction, add in some turbulence and the next thing you know you have a leak.
As your reading this please keep in mind there are things you can do to sacrifice or even eliminate leaks. They are relatively inexpensive and I'll tell you what they are in a minute.
When water pipes leak many things can happen - none of which are any good. Pinhole and slab leaks, mold, wasted water, wasted energy, property damage, resident/guest complaints and inconvenience all mean one thing.
It cost you time and money.
The only question left is how much? Please refer to Table 1 for an idea of how much a leak can cost.
Table 1: The Cost of a Leak
1 0 You caught the leak early and it wasn't buried in a wall or under a slab
2 ,000 The leak was in a wall and you caught it early and it was relatively accessible after tearing out some drywall
3 ,000 Same as above except you didn't catch it early and mold and light structural damage had occurred
4 ,000 The leak was underneath a concrete slab but you were able to pinpoint the exact location
5 ,000 Same as above except you had to chase the leak into other rooms
6 0,000 + The leak went unnoticed until person got sick and you got sued
So there is the doom and gloom. What's the solution?
Good question. The rejoinder is there are a estimate of things you can do. As you go straight through my list keep in mind that population only use hot water 15% to 20% of the time (based on a study by the California energy Commission).
First, check your water pressure. 40 psi is high enough for most 1 or 2 story buildings. Be sure to check it in several places to find the lowest pressure in the building. Typically that would be the point furthest from the water meter. If you don't have a pressure regulator, put one in.
When implementing this strategy do it in stages. Drop the pressure by 5 psi at a time and wait to see if you have any complaints. Shower heads and aerators already restrict flow to 2.5 gpm or less. Newer fixtures like the Evolve line of low flow shower heads have pressure compensating technology built into them and work just as well at low pressure as they do at high pressure.
Second, turn off the pump when no one is using hot water. That's right. I said turn off the pump. As I mentioned earlier population only use hot water 15% to 20% of the time. The pump only needs to be on when population need water.
There are 3 methods of implementing this strategy:
1. The hand-operated Method
2. The Guessing Method
3. The automatic Method
Manual Method
Have person go to the switch and turn on the pump when you need hot water and turn it off when you are done. Might be practical for a particular house home (certainly not convenient) but impossible in an apartment or hotel.
The Guessing Method
Plug your pump into a timer and guess when hot water will be needed. This may be a practical clarification if the estimate of population living in the house or apartment or with a microscopic estimate of guests in a hotel and everyone has the same predictable need for hot water. Unfortunately when hot water is needed during an off duration the timer gets disabled and never turned back on.
The automatic Method
Think about your recirculation line as a done loop. When there is no question for hot water, no water enters or leaves the system. When a hot water faucet is turned on there is a "leak" in the system.
When water leaves the theory more water is added from the city water line straight through a cold water make-up line (this is the technical name for the copper pipe that brings cold water to your water heater).
If a flow sensor is placed in the cold water make-up line, any indication of water movement would mean person is using hot water.
If the sensor sensed a question (i.e., person turned on a hot water faucet) it could turn on the pump. The question would be met and the pump could be turned off automatically when the question ended.
That is genuinely how an On-Demand tantalizing Pump Controller works. The pump is only on when there is a demand.
As it turns out, there are many benefits to automating your recirc pumps operation:
o Drastically reduces pinhole leaks and slab leaks - if the hot water is not moving, it is much less corrosive
o energy is conserved - since population only use hot water 15% to 20% of the time, the pump will be off 80% to 85% of the time. That means the recirculation line isn't full of hot water and no energy is being lost. California energy Commission studies indicate 37% less energy is consumed when an On-Demand Controller is installed.
Note: A sufficiently high speed pump is required (2,200 rpm or faster) to implement this strategy. If you have a high speed pump you will only need an Arc 100 Controller. If not you will need a full theory along with a high speed pump.
In conclusion, cut your risks, lower your losses, sacrifice your energy bill and increase the life of you pipes and water heater or boiler by turning off you recirc pump with an Arc 100 Pump Controller.

Duration : 25.68 Mins.DVD: www.amazon.com thefilmarchived.blogspot.com Hồ Chí Minh, born Nguyễn Sinh Cung and also known as Nguyễn Ái Quốc (19 May 1890 -- 2 September 1969) was a Vietnamese Marxist revolutionary leader who was prime minister (1945--1955) and president (1945--1969) of the Democratic Republic of Vietnam (North Vietnam). He formed the Democratic Republic of Vietnam and led the Việt cộng during the Vietnam War until his death. Hồ led the Việt Minh independence movement from 1941 onward, establishing the communist-governed Democratic Republic of Vietnam in 1945 and defeating the French Union in 1954 at Điện Biên Phủ. He lost political power in 1955—when he was replaced as Prime Minister of the Democratic Republic of Vietnam—but remained the highly visible figurehead of North Vietnam—through the Presidency—until his death. The capital of South Vietnam, Saigon, after the Fall of Saigon, was renamed Hồ Chí Minh City in honor of the communist leader. The 1954 Geneva Accords, concluded between France and the Việt Minh, provided that communist forces regroup in the North and non-communist forces regroup in the South. Hồ's Democratic Republic of Vietnam relocated to Hanoi and became the government of North Vietnam, a communist-led single party state. The Geneva accords also provided for a national election to reunify the country in 1956, but this provision was rejected by South Vietnam's government and the United States. The US committed itself to oppose communism in Asia beginning in ...
