Customer called in about running toilet. Upon arrival, discovered that toilet was running. Checked flapper and noticed a plastic ring on it and removed it. Customer mentioned he replace the flapper, but want able to get it to stop running. Noticed chain was really long. Chain could be getting caught between flapper. Adjusted chain and flushed toilet several times and no more running toilet. Did notice fill valve wouldn’t stop filling when it was supposed to. Check water pressure and water pressure at 110psi. Per code pressure should not exceed 80psi. Will return next day to install PRV. Replaced fill valve and supply line. While replacing fill valve, noticed tank was loose. Bolt is missing on one side of tank. Informed customer of findings and customer approved for toilet tank to bowl bolts to be replaced. While installing new ones, tank ended up cracking. Went ahead and replaced entire tank at no additional costs due to breaking on us. Checked for leaks and no leaks detected.
