Ring Seal Soil Systems
Ring Seal Soil and vent is the most commonly used soil system in domestic and non-industrial commercial properties in the UK.
Our FloPlast ring seal soil system is compatible with most other soil systems that are manufactured to British/European standard.
To install any pipe or fitting into another ring seal fitting, first make sure the end of the pipe has been chamfered. Clean off any dirt or debris and lubricate the joint with silicon lubricant. Push the pipe in squarely until resistance is felt, then withdraw it very slightly to allow for any potential system expansion.
