Condoms are NOT flushable. Only materials that can be broken down, such as Toilet rolls, are ok to flush down the Toilet. Condoms take many years to decompose and, if flushed, will likely get stuck in your drain/sewer and cause a blockage, so they are not suitable for flushing.
Even if your drain doesn’t get blocked after flushing a Condom down, the Toilet flushed Condoms cause problems in the main sewer and contributed to massive blockages, which then need removing by engineers.
‘Not my problem’, you may be thinking but bear in mind even if you get away with flushing condoms for a little while, you won’t get away with it forever. A blockage in your Plumbing that’ you’re responsible for is inevitable. So never flush Condoms down the Toilet, dispose of them correctly and sensibly, wrap them up and put them in the bin.
