Most folks take our drainage for granted; often we assume any issue that arises will be the responsibility of the water supplier. However though, in most cases, you're usually responsible for drains in the boundaries of one's property, while the sewerage company is in charge of lateral drains, which are beyond property boundaries, and sewers. Although most sewers are actually publicly owned, there are still some private or unadopted sewers. If your premises is served by one of these brilliant, you may be responsible for maintaining it.
So if there is a concern with the drain inside your property boundaries then it is your responsibility, and they, unfortunately, do block up for a variety of reasons.
Some signs that will assist identify a draining issue include:
1. If your toilet, shower, bath or sinks are all draining slowly this is likely a concern with the drain itself. Independent drainage issues will be an issue with the fixture itself. The bathroom . is often the primary driver for a blockage - if flushing the bathroom . causes water to rise in the shower, or running taps causes the water in the toilet to rise, then you've got a blocked drain on your hands.
2. Foul smells certainly are a dead giveaway for a blockage, if something has blocked the drain and begun to rot, you'll certainly find out about it.
3. Finally gurgling noises from pipes, drains and plug holes are warning signs of a potential blockage. You can find out more is created when the air is trapped in the pipes and waste water displacing it.
Typically the 2 biggest factors behind drain issues will undoubtedly be grease/fat build-up and tree root ingress. Fat build up is a large cause for blockage in the national sewer system and it'll affect homes too. When you wash your plates or just pour fat down the sink, the warm liquidated fat will hit the cold outside water in the drains then solidify, over a period this will build up causing a blockage.
Root ingress is harder in order to avoid, and most likely the biggest cause for blockages in homes. Root issues can be hugely serious and a big cause of subsidence related problems. Older clay pipes are particularly susceptible to root ingress as they are joined with just sand & cement these joints offer little resistance to fine tree roots which once inside develop into tap roots and root masses which then reduce the internal bore of the pipe.
