: : : According to all of the experts and technicians I have had, the polybutylene plumbing in my 9 year old home is the reason I have just installed my 3rd furnace. The class action suit people say no help because the pipes don't leak.

: : : I cannot keep installing new furnaces at this rate. Can anyone give me any information or suggestions?

: : ive nevere heard of this before. i think its time to try a new plumbing co. if this is a true situation i see no reason why a cast iron boiler shouldnt be the solution. i have worked in hundreds of houses with poly pipe supplying the water (both city water and well water) never had any bad come out of it. please keep us posted as to your outcome.

: Engineers at Weil McLain and Thermo Dynamics
: claim my polybutylene pipes which carry domestic, hot, and heating water is allowing
: oxygen to permeate my pipes causing rust and
: barnacles to ruin my boiler. Both advise I replumb with copper. Shell says no leaks, no problem.

: Have been advised to find oxygen permeation
: rate of pipes. Also told poly pipes not rated to carry water over 110 degrees. Pipes say 180
: degrees right on them.

: Any ideas where I can find these ratings?

: Thanks.

J: McGraw Hill publishes the "Piping Handbook" 6th Edition, edited by Mohinder Nayar, Engineering Specialist for the Bechtel Corporation. It gives the rating for polybutylene pipe manufactured in accordance with ASTM D 2581 as having a hot water rating of 500 PSI at 180 deg F. Ask the guys who are giving you all of the "information" to forward copies of the codes and studies they keep referring to. I suspect the silence will be deafening. Tony
