Hello. CPVC vs PEX for hard water can be a tricky choice because both these pipes have certain qualities which make them fit for hard water usage. Both of them can be used in hard water conditions. PEX pipes are not affected by the scaling process, which makes them fit to be use with hard water. On the other hand, CPVC pipes are corrosion-resistant and have a long lifespan with hard water usage. But CPVC is a bit better than PEX.
Hard Water Plumbing CPVC Vs PEX
I will share a detailed comparison between the two, which will help you decide which pipe to choose between CPVC and PEX.
CPVC | PEX |
It is resistant to chlorine and other disinfectants. | PEX degraded with chlorinated water over time. |
Has a longer lifespan. | As it is prone to degradation, its lifespan is shorter. |
Installation is tough as the pipes are rigid and solvent welding is needed. | They are highly flexible and easy to install. |
CPVC is much cheaper in comparison. | PEX costs more than CPVC. |
So, if you do an overall comparison, CPVC pipes do have a significant advantage over PEX. I would thus recommend you choose CPVC pipes over PEX.
