No he cured the problem your solutions would only mask the problem which
is the the pressure surge on start and stop of the pump. If the 20
gallon tank is designed for what he's using it for (i.e. has a rubber
bladder inside) none of your dire predictions apply.


It is your house, your budget, and your time. You get to choose
when and how you spend it.

Yeah, don't listen to this guy.

"that guy" happens to be right. The fix -is- a bandaid approach to a
non-problem if the system is installed correctly. Your concern about
water hammer is unwarranted or there would be pipes breaking all over
this land of ours.

Well all pipes will eventually fail.

He said he eliminated the pressure surge and that was the only reported
problem. Simply moving the pressure switch to where the pressure surge
doesn't exist wouldn't get rid of it. And no, the pressure surge won't
cause his new pipes to fail immediately, but in 20 or 40 years when the
system becomes brittle it will make a difference.
What about this system do you think is not installed correctly? The
surge is caused by the long run from pump to the holding tank. Moving
the holding tank would also eliminate the surge. But putting a surge
tank by the pump also works. That's why plumbing supply stores sell them
in all different sizes.

No, he did -not- say that he eliminated the surge. The surge is still
there but being absorbed by the surge tank, just as it was by the tank,
just as it is in all systems. There will always be a surge at startup
given any pipe at all between pump and tank.

"move to where....surge doesn't exist"??? This is a hydraulic system.
The surge will affect all parts of it.

The surge will NOT (how many times do I have to say it?) affect the
pipes. You are confusing a surge with a water hammer - two different
things. It is a water hammer that causes damage.

Again, adding something at the well head without doing anything else is
a band aid approach to fix a problem that wouldn't exist if it was
correctly installed. Curing the problem by adding unnecessary
equipment is a band-aid approach and poor mechanical work. Were it my
well I might do it but not on any other well I work on (of course had I
installed it, the switch would have been on the tank). There is a
right and wrong way to go about fixing things.
