How we work
It's a mezzanine floor, the interior patio drain is blocked and the downpipe is poorly constructed; we believe the entire installation needs changing. Every time it rains, it floods. This is a communal work, we need a quote for the community president. After flushing the toilet, meaning operating the cistern flush. The cistern refills, then water starts coming out again, forcing us to close the stopcock... The flush mechanism has a button. I apologise if I'm not explaining it correctly, as I lack technical knowledge. In any case, I have bought a replacement rubber seal (rubber/plastic ball with rod and nuts) but due to difficult access, I would like a professional familiar with this type of work to install it. Therefore, I'd like to request a quote.
