Greetings,
I have a new (Jan.) 4-ton Carrier 50YDV GT-PX geothermal heat pump
installed in my home. Water is supplied from a Constant Pressure 75
Pump by Fanklin with a 4 gallon (bladder?) it is connected to a 3/4 hp
pump in a 370 ft well.

The problem is that there is a build up of pressure causing
ruptures in the water line on the geothermal line. The plastic drain
valve of a Rusco filter has split twice. It was replaced with a brass
drain valve, the pressure then went on to split the solienoid. The
company that installed the unit is going to add in a pressure relief
and a hammer(something), and see if this solves the problem.
They haven't experienced this before and its the first time they
hooked up a geothermal system to a Constant Pressure drive, they
normally are used to working with the well tanks.

Has anyone seen this type of thing before? If so can you describe
what was going on so I can relay it to the installers? Will doing the
work on the geothermal side push the pressure to the water lines in the
house causing ruptures there?

Any help would be appreciated, the installers seem pretty good but
they are stumped on this one and are calling a few different places to
ask around about this problem.

Thanks

I forgot to mention there was an 8gpm limiter right after the solenoid
to control water flow, not sure if it makes a difference.

Yes, I know, but its going to cost you for the info.

Does a university give away its education for free? If they can be paid for
it we should be too.

Let me know if your willing to pay for the answer

Answer his question and Ill pay you. Then afterwards make you you pay
for your answers when you ask questions. Or you could just answer him
and not be such a selfish pig.

Nope, I will answer other trademen but not homeowners.
Besides, if Universities can be 'selfish pigs' then so can I.

I KNOW the answer and I KNOW the cure.
