Here is my problem. My water bill is double that of my neighbors. Since we have similar sized houses, families, and similar lifestyles, I think I have a leak or some other plumbing problem. My neighbors pay $40 - $45 per month. I usually pay around $90. This has been going on for a few years (but I did not know it was a problem until I asked what their bills were).
I shut off the main water supply to the house for a few hours and noted no consumption on the meter. Therefore, I do not think the line from the meter to the house is leaking. I believe the problem is inside the house.
I have tested my toilets by putting dye in the upper tank. No leaks. I was informed I could have high consumption if the float in the toilet tank was set to rise too high, letting water fall into the overflow drain. I checked. One toilet was set to let the water rise pretty high but it was below that overflow drain. I adjusted it to have the float cut the water off even lower anyway.
I have replaced the flapper and the float in both toilets.
I do not have a pool or an irrigation system. Even though something is using a lot of water, I don't hear water going thru the pipes when it shouldn't be. In other words, if water is being used, the washer is in use, the dishwasher is in use or someone flushed a toilet.
My house is 15 years old. We have all the same appliances and fixtures as when it was first built. I have a dishwasher, clothes washer, electric water heater. The fridge has an ice maker.
That's my story. Any ideas? What would you do? I am thinking of shutting down one room at a time that has some water consuming appliance to try and isolate the issue. That will take time and be a pain. Any better solutions?
Thanks for reading.
