I've noticed over the last 4 months my combined Amenities/Water/Sewer bill has gone up about $20 each month. In March it was $235.00 and this month it is up to $272. I was just wondering if this is normal or if it may signify a problem (and what may be the cause)? I have no problem if this is a normal occurance, maybe the time of year or something, but want to have it fixed if there is a problem. Thanks in advance. I do have tenants in my house but they have not been doing anything unusual and they checked to make sure nothing is leaking.
