Urinating in washroom lavatory (sink) to save money on water usage
Does urinating in the washroom sink in order to save money on water consumption (by not flushing the toilet, which uses about 6 litres of water per flush) have any affect (corrosive or otherwise) on the drainage pipes. I always follow up by running the water in the sink (max. flow) for about 3-4 seconds, wait for the water to flow down through the trap, then run a second time (max. flow) for about 6-7 seconds. I'm saving 4.5 to 5 litres of water every time I urinate! Any comments?
