Hi all
I'm thinking of installing an NRV in my houses main sewer line to avoid backflows from the street's main sewer during intense rainfall.
I know there are loads of pros/cons/pitfalls etc - and I'm getting a bit dizzy looking into all the options.
Does anyone have any practical experience of installing and/or living with one of these?
I like the idea of an open one (one of these in a new inspection chamber) so I can spray it, rod it etc to keep it maintained without getting down and dirty with bolts and lids etc. The head of water I'm dealing with would be OK with this setup.
However, most places only seem to sell/recommend these - which look like they have so much potential for going wrong - then being impossible to repair without hugging it to get access to the internals.
I also don't like the idea of those retrofit jobs - where you just slot them down the pipe - they look to reduce the capacity of the pipe and introduce too much of an obstacle. My overall sewage line gradient is very low.
