Guides
Straight answers, off the same sheets the rates come from.
Every answer here can be traced to a supplier’s own price list or to a rule we publish. Where we do not know, we say so instead of guessing.
What is the difference between SCH-40 and SCH-80?
The wall thickness — same outside diameter, so the fittings are the same, but you cannot tell them apart by looking. The schedule is stamped along the pipe; read the stamp.
What sizes do you carry?
Everything from half an inch upward, plus the metric PPRC range in millimetres — and every spelling of a size finds the same rows, however your own sheet writes it.
How much is pipe per foot?
The whole pipe divided by 19.75 — because a six-metre length measures three inches short of twenty feet, which is what our supplier says his own pipe is.
How many pieces come in a carton?
It depends on the fitting and the size — the smaller it is, the more the carton holds — and the count is printed against every row whose company gives one. Pipe is not sold by the carton at all; it is sold by the length.
What do PN-16, PN-20 and PN-25 mean on PPRC pipe?
The pressure class — the wall thickness for the same outside size, printed by the maker against the DIN 8077/78 standard. You choose it on the pipe; every PPRC fitting we carry is PN 25.
Which pipe can I use for hot water?
CPVC and PPRC both carry hot and cold water. UPVC does not — it is a cold-water and drainage pipe, and it is the one people buy by mistake.
