It is an easy to use dip strip that tests central heating systems for the correct concentration of inhibitor, to ensure that the system is fully protected and sludge and debris is prevented from forming and building up.
Is it safe to empty central heating water down the drain?
You should only drain central heating system water into the foul water drain or a septic tank. Never drain system water into road drains or rain water gullies as these go directly into rivers. Never pour water from a central heating system onto the garden or lawn.
