We have 2 upstairs bathrooms and a downstairs shower room and an understairs loo
The under stairs one rarely got used before but since the flush handle fell off, it hasn't been used for months. You have to remove the top and pull the lever by hand
This week, we noticed a bad smell and traced it to this loo. The cistern was full of stagnant water as it hasn't been flushed for a while. What is the best thing to put in the cistern to keep it fresh? I think I will get it taken out in the summer but need something in the meantime in case I forget to flush it regularly
