Arrived to troubleshoot 3 issues. Female bathroom sink has very little water coming from the faucet. 2 toilets making loud noise at times. Then no hot water in either bathroom. Cleaned out aerators in both sinks, solved left sink issue and cold side right sink issue. Possible stop and supply issue. Toilets all functioning appropriately at this time. Power flush, possibly had air in the system. Hot water works in all sinks but takes time to get hot. Recommend tankless flush, or possibly replacement of 10 year old tankless.
