Morning all. I live in large victorian semi-dettached property. Between the two properties is one fall pipe running down onto my property linking into a standard square hopper 110mm pipe/p-trap then 110mm pipe into the main street drain. (distance from house to street drain approx 3m). No other connections go into this at present. No issues occur with light rain but any moderate/heavy rain causes the hopper to over flow. The pipe has been rodded right through to the main street drain on numerous times and the p-trap is clear so it appears that the p-trap/current setup cannot cope with the flow of water. I've been looking at replacing trap with a bottle gully. Any ideas if bottle gullies might cope with a higher flow rate of rain water? If not, any other suggestions?
