PVC pipe is rigid pipe and comes in 20-foot sections. The ends of the pipe are typically pre-threaded. Stainless steel couplings are used to hold the sections together and make a watertight connection. This type of pipe is very strong and can withstand the stress of a submersible pump hanging from a long run of piping.
What do I do if my well casing is cracked?
There are two ways that a well specialist might fix a well casing: First, for above-ground damage, they may suggest repairing the pipe and extending it upwards so that it’s easier to see and avoid in the future.

Which PVC plastic pipe to use?
– Conveyance of drinking water: Hygienic requirements – Conveyance of gas: Highest Safety requirements – Plastic pipes for radiant heating and floor heating: Temperature resistance over decades – Sewer applications: High chemical resistance
Should I use PVC or CPVC pipe?
There are many cases in which paying a higher price for CPVC doesn’t offer any additional benefits. For example, PVC is often recommended for cold water systems, vent systems, drainage systems, and irrigation systems.
