Your pump may be loose and moving/twisting around when turned on. First- Fix pipe then maybe put rocks around it to keep it from moving, the tighter the better.
Answer
make sure you are using the correct PVC weld glue. this is a big factor and one can never use enough glue. really lay it on. and make sure you give the glue at least 12 hours drying time before turning anything on regardless of what the packaging says.
plates puled apart
No, pulling the ends directly apart won't create the same pattern. The pattern is a result of the specific folding and layering of the material, which pulling the ends apart does not replicate.
Plates pulling apart.
It dissipates when you are pulling something apart.
A pulling apart force is typically called tension. This force occurs when two objects are being pulled away from each other.
When two plates are pulling apart, it is known as divergent boundary or divergent plate boundary. This type of boundary results in the formation of new crust as magma rises to the surface and solidifies.
rift zones
divergent boundary
no but coliding plates create volcanoes
Your best way of finding that out is to go to a good hardware store and looking. Apart from pipe wrenches most plumbing tools are too hard to describe
The force pulling a material apart is called tensile force. It acts along the axis of the material and tends to stretch or elongate it. Tensile force is resisted by the material's internal structure, such as molecular bonds.
It could be that they don't want the tooth to break apart while pulling it out
