Bury the damned pipe. Thus saving energy, water and relays.

Hmmmmm....interesting thought...could blow the hot air off a lite bulb
with a computer fan from the pump house, if snubber doesn't works then
maybe can rig something up like that..should have the components for
snubber next week...got my fingers crossed, as that is the least
expensive/easiest to do..not worried about pump as has lasted well over
10 yrs., will see...thanks for the thought.....have fun.....sno

What we use up here in the Frozen North of Alaska is similar to this
Morris... We have our Galv or Copper waterpipe with a wrap of HeatTape,
then wrap that whole deal with Pipe Insulation. then we put that inside
a 2" PVC Pipe that was split in half and  we use Stainless Hose Clamps
to hold the PVC around the system and bury it about 4 feet down. When
the Temps go below 0F, with no snow cover, or -20F with snow cover, you
just turn on the Heat Tape, that is usually about 1.5 Watts/Ft, whenever
the Genset is running. Works good, clear down to -75F...

As others have mentioned, the relays used (I ASSuming you are talking about
the "start" relay) usually last a LONG time as they only operate and release
ONCE per start cycle.

What can greatly reduce the life is "false starting" by which I mean that
the pump starts, the relay opens but there isn't quite enough torque
available to bring the pump up to full speed.  It slows down and the
"starting circuit" is once again activated.

You can check this simply by watching the relay when it starts.

It could well be there is "something" wrong with the capacitor.

The 'next time' you might get an entirely new 'control' box and ensure that
all accessible connections are tight.
