It was too bad that the New Simple Volume, New Spanned Volume, New Stripped Volume, New Mirrored Volume, New RAID-5 Volume greyed out so that you cannot create new partition with this unallocated space.
The cost to add sewer backup could range from $10 to $250 per year with traditional home insurance policies. Not all insurance policies (or homes) are created equal. Some companies allow you to add sewer backup to your policy, but will limit the amount of coverage to $5,000.
In addition, the sewer bill is based on water usage. Hence, the incremental cost of 1,000 gallons of water and sewer use is $5.40 for water and $3.50 for sewer (2013 rates), for a total cost of $8.90. This total cost equals 9/10ths of 1 cent per gallon. A leak can be costly and can add up quickly.
