Roto-Rooter, the nation's leading expert on plumbing issues, reports that the plumbing systems in American homes and apartment buildings use P-traps
similar to those in Hong Kong.
The most common reason is that people don't have the U- or P-traps
(beneath sinks or showers) installed correctly," Jones said.
Fitting styles include couplings, 1/8 and 1/4 bends, wyes, combination wyes, pipe increasers, caps, p-traps
, clean-outs, and reducing wyes and combinations.
FMN Industries also offers P-traps
, sumps and other sanitary fittings for those drains requiring maximum corrosion resistance.
