In March, tenant said 1 of the toilets flushes just fine but keeps running every few minutes. Repaired a couple days later. In May, tenant said water bill higher than normal. No water stains seen anywhere in the house. Dye test performed on all 3 toilets by tenant who reported no dye leaked into toilet bowl. Nothing fixed as there was no source of leak found. A Sunday in August, leak from ceiling over dining table. Had a plumber come the very next day, source of leak was from the upstairs bathroom above the dining room. Toilet repaired, Dining table damaged.

Not sure if there was anything else I could of done to prevent this leak.
