Because there are many documented cases of pipe and fitting failure, some insurance companies are requiring that the PB or PEX pipe be replaced with another water piping material before homeowners / hazard insurance can be written.
Remember that without hazard insurance on a property, lenders will not approve and fund mortgage financing.
In the upcoming edition, we'll go into the history, background, and current status. Please be aware that these types of piping should be mentioned in the Seller's Disclosure when known.
While PB was used in new construction between 1978 and around 1995, then stopped being used, PEX is still available today. PEX may be used in both new construction and in repairs or add-ons by licensed plumbers and DIY homeowners.
It's important to note here that PEX is an approved piping material under the Florida Building Code 5th Edition (2014), provided that both the pipe material and fittings meet specific ASTM-tested standards.
PB is no longer approved under any building code that I could reference.
The main issue with both PB and PEX is the use of crimp-style clamps that secure the flexible pipes to junctions and fittings. Newer, more reliable fittings are now being used for installation, though without a detailed inspection, many insurance com-panies assume the more leak-prone crimp fittings were used.
They are managing their risk exposure on flexible residential piping with a very broad stroke.
Because many insurance companies have stopped insuring houses with PB and PEX against damage from plumbing leaks, home inspectors are keying on this and actively looking for both types of plumbing.
Next week, we go into detail on this topic so you can discuss it with your sellers and buyers. Stay tuned...
