Installed two client supplied pressure assist toilets in the upstairs and downstairs men’s room. The downstairs toilet flange needed to be replaced. Both toilets are functioning properly at this time. Completed minor repair on both Delta single handle lavatory fixtures in the men’s room downstairs. Repair included new seats and springs for each. Both are working properly at this time. I was unable to replace the thermal expansion tank due to the CPVC ball valve not turning.
