-To existing and new home owner you must always be aware what type of pipes are in your homes.
-clay pipes & cast iron are prone to blockages and they weather easily, which will lead to you calling a plumber to unblock the drain every now and then.
-best thing to do would be to replace them with pvc piping which is cheaper and durable.
-also putting filter by your gully head will help prevent food stuff or dirty going down the drain and creating a blockage.
-Avoid switching on and off the circiut breaker for the geyser by the main, for it will lead up to the element getting burnt.
-instead install a geyser wise system that will control both power and temperature, this will save you money and prolong the life of your geyser.
