I share a well with my neighbor we have 2 dwelling condo. My unit concest
of myself, and her unit has 3 people as of now. We share the following
which are all connected to my electric Meter... well pump, water
conditioner system, electric base board heater
that keeps the pump room warm during the winter all in a room in my
garage. Also a sprinkle system that shared on the front property. It's a
50/50 shared property. She had nationally agreed with hand shake when
she bought the unit next to me back November 2014, I came up with a
charge $ 50.00 which she agreed and was paying this till past May 2015
she stopped paying her monthly obligation To me. I was willing to drop
the price down, she putting up a fight. She is reneging On everything, I
had no choice put to seek legal advice and the issue is still not
resolved. She wanted to use a kill- a- watt gizmo in my garage, I'm
Not her landlord to be checking each day that this gizmo is
functioning Right, and again given her the convenience Every month
timeing this and
that off my electric bill. I think not... It's not the long term solution,
especially if I want to sell my unit no one wants to be involved with a
gizmo. Then my neighbors chopped up with a internet chart from Runstone
Electric Association energy from
Alexandra M,N from 2014, We live here in New Jersey not M,N. The chart
says it varies from family to family. She only wants to pay $ 15.00 a
month for her Calculations We're wrong from that chart, also there was
no mention how much a sprinkler system runs on electric, my neighbor has
no idea.... I think the best solution would be a second well... Do you
have any other ideas, well can be costly, she would have to pay half
since it's a shared property..

So, you are overcharging her for her half share of the electricity and
if she wants to measure actual usage you come up with:

"I'm not her landlord".
"checking each day that this gizmo is functioning Right"

No sympathy here.
