Meanwhile, with a change of the water pipes is consumed a smaller amount of water for domestic usage since the fresh water comes faster. Moreover, as the time passes the old pipes are prerequisite for various accidents - narrowing of the internal bore due to clogging and increasing of the pressure required to move the water through the vertical and horizontal elements of the conduit.
The old pipes often break down - parts of them or their connecting elements decay and cause leaks of different intensity - from constant dripping, through spraying and large leaks. It is especially unpleasant when the accident causes flooding in the building.
At the replacement of the water drainage system in residential buildings, the old plumbing installation is removed and a new circulator installation is placed.
The advantage of the water circulation system is that the hot water is rotating within the installation, and with turning the tap of the hot-water it flows almost immediately. In the old water supply systems, the hot water does not circulate, but each time it is coming from the basement, which takes some time, especially if the hot water needs to reach the upper floors of the building.
During this time the cooled (even cold water) which passes through the pipes is being billed as hot water. This leads to high costs for hot water, which is not actually consumed as supposed to, since it was cold.
The payback for the replacement of the old water supply system with a new circulating water system will be paid within one to two years.
The situation is similar with the sewer installation. The older buildings come with sewerage systems that are made of stoneware, which over time become unreliable, crack and start causing various problems - leaks, obstructions, presence of cockroaches and other pests, etc.
With the change of the stoneware with UPVC pipes, the toilet must be replaced as well. The stoneware sewer systems require installation of toilets with vertical drainage, while the modern sewer systems require installation of toilets with side or rear drainage.
