aymaq 0 Report post Posted July 13, 2016 I have issue on my both toilets where the water pressure very low especially my Master Bedroom Toilet. It will be even worst if someone uses another toilet at the same time and will experience even lower pressure. I'm staying at the highest floor and I'm using a instant water heater. Anyone, who has a rectification to this issue that I am currently facing, pls advice. Cheers! Share this post Link to post Share on other sites
