It's no secret that at least once in a lifetime you can forget the water included in the bathroom. And so that such forgetfulness does not cause large material costs, all models of baths are equipped with a security system, whose task is to save housing from flooding - drain-overflow. We will talk about different types of drain-overflow system for the bathroom today.
Which drain-overflow for a bath is better?
Bath safety systems can be divided into three groups:
- Traditional plum-overflows , which are a system of two drain holes and cork on the chain. One of the holes is located in the bottom of the tank, and the second - in the side wall, and among themselves they are connected by a system of flexible hoses. The structure of the traditional drain-overflow system includes the following elements:
- drainage neck installed in the opening in the bottom of the tank and connected to the sewage system by direct discharge;
- overflow neck, installed in the hole in the side wall and connected to the sewer system by means of a lateral branch;
- siphon;
- The corrugated hose connecting the overflow neck with the siphon;
- Pouring tube to drain water from the siphon to the sewer.
Such plum-overflows are traditionally made of plastic, but despite this they have a fairly long service life. The advantages of the traditional drain-overflow can be attributed to their low cost and ease of installation. The only thing that the owner of such a system will have to face is the need for regular replacement of gaskets.
- control unit, which is a rotary lever or ring and serves to raise and lower the plug;
- a cable with which the control unit interacts with the plug;
- cork.
Speaking about the merits of semi-automatic drain-overflow systems for a bath, one can not but note their presentable appearance - the side drain hole is hidden behind the control unit, which can be made of bronze, various alloys or plastic coated with "gold". Convenient and control system of the plug - to remove it from the bath no longer need to bend low and wet your hands. But all these advantages are completely crossed out by the low level of reliability of such systems - they very quickly fail. This is especially true for inexpensive models of unknown Chinese manufacturers. From this it follows that in the case of a limited budget it is better to give preference to traditional drainage-overflow systems.
