What is this for?

[jkogel]

Pic #1 - Poly, pex and cpvc pipe. Pic#2 - poly compresion fitting from early '90's. Some "plumbers" are still working with grey poly, using up old stock!! - a couple of months ago, found a new Hot Water tank installed with polybutylene.

For what its worth I have seen this on houses only with septic and well.
Anyone have any other feedback on if this is the correct or not??

Thanks

Try this Troy. http://www.polybutylene.com/poly.html
If you find Polybutylene pipes you need to call it out.

Troy, To your specific question, read my post #8 in this thread.

See this thread Post #8 for this issue.

my question was referring to the original pic of the bistribution cetner for the piping not the Poly piping sorry for the confusion.

See it on better homes in our area....doesn't matter the jurisdiction. Locally it's know a the "home run" system since every fixture has its own non-jointed supply lines from the manifold to the fixture........hence the term "home run".

Exactly. Radiant heat uses manifolds for the in-floor heating tube distribution. I've worked on a lot of houses with this type of heating, sure cuts down on the heat bills.

From the Radiant Design Institute http://www.radiantdesigninstitute.com/ )

SOME FACTS ABOUT RADIANT…
Q. Is radiant more efficient? A. If you mean will it cost less in fuel cost? The answer is not always.
If the house is small to medium sized and very well insulated or uses some of the advanced construction methods you will not save with radiant heat.
(My Note: In the past when houses were not well insulated and drafty, radiant heat might provide some extra comfort and hence, people would not run to turn the thermostat up to compensate for the house inefficiencies. With today's much better and efficient designs(if truly quality-built with better windows, airtight, no insulation misses,etc.), the comfort levels will be much the same from house to house. It then really doesn't matter the heating system type installed (except for local fuel costs); the house will need the same amount of heat to be comfortable. I find that manufacturers, sales types and installers use the radiant heat/warm floor /up to 50% savings argument and abuse their customers pocket books!!!)
If the house design is not adjusted to the requirements of radiant heat.
If you use a non-modulating or cast iron boiler you will increase your fuel costs considerably over forced air.
The radiant heated house must be insulated differently to be efficient. A heated floor can lose as much down as up.
Buying the wrong equipment can shorten the useful life of very expensive equipment or damage your home.
Improper or lack of insulation under a slab can cost much more than forced air heating.


From a study of Habitat for Humanity homes in Schenectady, NY:
Results:
Radiant Floor Heating System

• There was a considerable amount of engineering and design support and a significant amount of coordination required between the manufacturers, designers, and installers of the radiant floor system. For example, the system required a minimum loop return temperature to avoid condensation in the boiler, but the flooring required a maximum temperature to avoid damage to the finished flooring.
• It was very difficult to find a small-capacity, high-efficiency, moderately priced boiler for the radiant flooring system.
• The radiant flooring distribution system was easier to route and required less floor space than the forced air system.
• No significant difference was found between energy usage of the two heating systems.
• Trades working in the house after radiant system installation must be careful not to puncture the tubing. For example, when installing underlayment or toilet flanges, short screws must be used.

OK, so what would you make of this piping? A different property...

Again PB2110. Should have all appropriate comments.

This was in another inspection. The piping had been mostly painted over with white paint, but got this length - couldn't see any of the telltale markings...
