I think it is important to clarify a few issues being raised with regard to PermaFLOW (previosuly branded as Please Trap). Also, the pictures attached to the previous threads are not PermaFLOW, I am attaching the right picture. For an average homeowner, clogged sink is a pain, frustration and something that occurs more often than needed and the cost and time required to fix it is not just about the cost of an average P-Trap. PermaFLOW has the potential to solve this issue for a lifetime with minimal preventive maintenance. PermaFLOW is transparent and therefore allows the property owner or maintenance company the ability to see what is going on under their sinks. Its Self Cleaning design creates significant flow turbulence (upto four times the velocity of inlet water velocity - this is not required to be done manually as suggested in one of the previous replies), minimizes deposition, breaks and propels debris and cleans itself thereby not allowing the sinks to get clogged. PermaFLOW also has EZClean feature that helps clean the potential clog build-up easily without the hassles of using plumbing snakes, plungers, opening P-Trap and/or the use of harmful drain cleaning chemicals by using an external knob with a spindle and wiper inside for clean-up. Due to its unique ability to clean-up without the need to use Chemical Drain Cleaners, PermaFLOW is ââ¬ËGreen by Designââ¬â¢ and helps reduce the nasty effects of chemicals, both to the environment and the property owner. PermaFLOW also works well with Low Flow Rate Fauctes (1.5 gpm or even lesser) where a traditional P-Trap has tendency to get clogged much easier. PermaFLOW therefore adds significant GREEN Value to the property, community and the environment. Further, due to the fact that with PermaFLOW the debris is being broken down and propelled out and never a large clog getting built inside the P-Trap (with little preventive maintenance), therefore the probability of getting clogs downstream of the P-Trap is also lower. PermaFLOW is designed and manufactured in the USA and has been tested under extreme high traffic environments, has undergone IAPMO testing and is UPC Certified for US and Canada as well as certified to be compliant with IPC and IRC. It is built using transparent premium quality ABS Plastic and is therefore superior in finishing and longevity and provides a clear view in order to retrieve lost valuables. Unlike brass and chrome P-Traps, PermaFLOW is corrosion resistant. You can visit www.permaflow.com for more information on the product, testing and certifications.
