Replacing cast iron sewage on plastic lover Overhaul in the apartment should be carried out with the study of the state of sewage pipes. For a long time during the construction of houses for these purposes, cast -iron pipes were used. Cast iron itself is very durable. And in some places the pipe from cast iron stood for more than a hundred years. But this is only if they were covered with enamel. Enameled cast -iron pipes differ from the usual purity of the inner surface. And this prevented sticking on the walls of various deposits from drains. But if there is an opportunity, then during major repairs, any cast -iron pipes, even sunbeds, even risers, are better to replace with plastic.
The purity of the surface of the plastic is close to the glass and neither fats nor solid particles are besieged on them. Plastic sewer pipes are made of polyethylene or polypropylene. For each size, manufacturers offer a complete set of fittings. What to choose for the repair of intra -house and outer sewage, see here.
You need to carefully calculate how many meters to buy, which fittings to purchase. It is necessary not to forget that in each connection there should be a sealing rubber ring of a special profile.
Dismantling the old cast -iron sewage system will require great effort. Especially in the places of connections that were previously melted with molten gray or cement traffic. If the pipes cannot be disconnected, then remembering the fragility of cast iron, you can break it with a punch, observing the safety rules. After dismantling old structures, you can mount new, plastic.
In standard apartments, straight sections can be easily selected from pipes available for sale of different lengths. And if you need to cut them, then this can be easily done with a hacksaw for metal or a locksmith knife. If you try to cut the pipe with a “grinder”, then from severe friction the plastic can heat up to the temperature of the deformation and it will “swim”.
By decomposing on the floor all the details of the future sewer, you need to lubricate the joints with a thin layer of any lubricant or oil. This will facilitate the assembly. Having kept the necessary slope, you need to collect all the details in a single design. In direct sections of the sewer, you need to lay stops through each meter so that it does not bend under the weight of water. Otherwise it will violate the tightness of the connection.
The collected system of sewer pipes should be tested by pouring a large amount of water from the bucket into the farthest sink, and at the same time releasing water from the bath. During the drain of water, you need to carefully examine each compounds for water flow.
