Homeowner states that he went to the guest restroom located between kitchen, laundry room and garage and could hear water running through the wall next to the toilet and called us to see if there is an issue. Upon arrival homeowner greeted and showed me to the restroom and I could hear some water running but normal when water is running thru the pipe system. I asked homeowner to show me the location of each toilet and I check all the toilets and non were leaking the only drip came from a vanity faucet from an upstairs bathroom. I also checked the pressure and it is normal and I then went back to check in the first floor restroom and I couldn’t hear the water running anymore. Lastly I checked the hose bibs outside but both don’t leak and homeowner also couldn’t hear water running either and is satisfied that I couldn’t find any leaks. I explained that if there is any water bill increase that I could come back but for now there isn’t anything I could find leaking.
