I'm afraid I work installing central vacuum systems. When we install
vac pans we use a flexible rubber hose called VAC-U-FLEX, made
by Flexible Technonogies. I started using it at other times too, when
it's hard to get regular fittings down through the floor...it can save a
lot of time hammering and chiseling, and then trying to get the fittings
down through the hole. I told the boss about that, and he said not
to do it. The reason is because the tubing supposedly breaks down
after about 10 years, and if it's in a wall it's hard to get at and replace.
When I asked him why we use a product that breaks down in 10
years on vac pans, he said because we can usually get at them
to replace the hose. I don't think so, but we disagree about many
things. The question is: does anyone know if this product really
does break down after about 10 years, and if so, is there a similar
product that does not?
Thanks for any help!
