How to Prevent Blocked Drains
What are the things you can do? Regularly pour hot water down the plug holes. This will help prevent debris or nay type of build up from forming in your drainage system. Refrain from flushing disposable items down the drain. This includes nappies, tampons and tissues. Throw them in the trash bin instead. Regularly check outside drains to make sure that leaves and other debris from the garden are not blocking them.
For some people flushing down fat or oil down the sink is just something which they cannot avoid. If this also rings true to you, you should at least pour hot water down the sink with plenty of detergent. This will avoid encrusted fat from forming on the sink and causing potential blockages.
