What do sanitary siphons of and how look after them?
At first did siphons only of cast iron. Then there were more graceful siphons from copper alloys - bronze and brass. As brass cheaper and more technologically, siphons from it enjoyed popularity. Especially with the covering applied on them from brilliant chrome. Such siphons are reliable and do not rust, however over time become covered from within by a layer of oxides to which dirt begins to cling that complicates work of a siphon. There are also steel siphons, they are also reliable and convenient.
Recently siphons make of plastic - polypropylene or polyethylene. Plastic siphons are much more practical than metal. They it is easier, practically do not detain dirt, do not rust, do not decay, do not rust. It is possible to get a siphon from white, black or color plastic, and it is possible to buy a siphon with a brilliant covering, not distinguishable from metal. One more advantage of plastic before metal - coefficient of linear expansion. At plastic it is one hundred times higher that allows to simplify process of its installation as additional sealing materials are not required. However this advantage can turn back a lack of conditions of sharp temperature drop. In the place of a joint of a metal pipe and plastic the last can collapse. And still plastic siphons so far out of competition.
As well as any device, a siphon demands personal care, let and minimum.
For example that the large remains of food did not get to a drain siphon in kitchen, it is necessary to put a special grid in a drain opening of a sink. Well once a month to wash out a siphon hot solution of the calcinated soda (1 tablespoon on boiled water liter). In shop it is possible to buy also special detergents for a sewerage clearing.
More considerably the siphon should be cleaned so: under a siphon to substitute a basin or a bucket, to unscrew a nut in the lower part of a siphon and by means of a thick curved wire to take garbage. After that to put the clamp and for several minutes as much as possible to open a water tap that a strong stream of water it is final to wash out a siphon. By the way, among garbage there can be also valuable things, be attentive!
If from a siphon everything is the smell makes the way, it can be caused by several reasons. For example, the sewer pipe is littered lower than the level of your siphon and drains flowing from above force out air from a sewer pipe, and it probulkivat through a siphon. In this case it is necessary to clean a sewer pipe. Perhaps and such situation: discharge from neighbors from above goes a dense stream and exhausts water from your siphon. The water lock disappears, and smells freely get to you. In that case it is necessary to change a siphon on bigger by the sizes.
If the sink is badly left by water, the siphon is perhaps guilty. Check how exhaust pipe of a siphon comes into a drain pipe, - can it rests against a wall of a sewer pipe and partially blocks it.
At installation of siphons it is desirable to use the accessories manufactured by one producer, differently from - for disagreements of details there can be a leak. You should not use corrugated hoses in the rooms which are not heated during the winter period since they are made from not enough frost-resistant materials.
