Press-fit piping systems are relatively new to market when compared with traditional copper piping, so it makes sense that there might be a few lingering misconceptions around its performance. Here we bust four of the biggest myths:

Myth #1: Press-fit piping is very costly

This one gets bandied about but it is very easily debunked. When you compare the overall installation costs, stainless steel plumbing systems work out cheaper. Copper piping requires specialised labour to install, which makes the finished job a lot more expensive. With no requirement for qualified welders, stainless steel press-fit systems are extremely fast and simple to install.

Myth #2: Press-fit piping is a lot more expensive than copper

This misconception is also incorrect; when comparing pipe it is sometimes much cheaper than you would expect, especially 304L grade pipe. With soldering now a thing of the past with press-fit systems, an overall cost comparison of both options looks like this:

Average cost of copper piping: 12mm – 101mm: $68 - $890

Average for 40mm: $300

Average cost of stainless steel piping: 15mm – 168mm: $33 - $1400

Average for 40mm: $280

Myth #3: Press-fit piping has higher rates of leakage

Wrong, wrong, wrong! We can absolutely guarantee that correctly installed press fit technology will not leak. Being able to check that all fittings have been pressed ensures that there are no weak or vulnerable connections in the system, and makes sure that all joints are successful. This reduces the risk of human error and enables accurate checks to be made.

Myth #4: Press-fit systems have the potential to come apart under excessive pressure

When installed correctly, Stainless steel press-fit systems have varying burst pressure thresholds, depending on the size of the pipes. To ensure that press-fit plumbing is installed safely it is important to include pressure relief valves in every system. These connections are capable of withstanding very high temperatures and high pressures, an engineering feat that has been certified by countless international test results and certificates.

Piping Comparison Guide: Welded Copper VS Press-fit Stainless Steel

Copper is generally perceived as the industry standard for piping given its long and distinguished history, so you might be suprised to know that newer forms of technology like stainless steel pipe fittings are superior in a number of ways.

This guide will dispel some common myths and provide you with a clear and concise comparison of the primary featuresand benefits of each option.
