First, PPR plastic water pipes leak.
1. First saw off the leaking place, and the saw mouth should be flat.
2. Lightly polish the newly exposed port with sandpaper, not too much.
3 Wipe the port clean with a clean cloth.
4. Apply the special glue to the port, let it dry for a while, and then apply the glue to the "bamboo joint".
5. Connect the port with a "bamboo joint" and turn it repeatedly until it is firm. Connect the other end in the same way.
6. After everything is finished, apply a proper amount of glue to the joints to ensure no leakage.
Second, PVC water pipes are leaking.
1. If it is a PVC water pipe, you can buy a PVC water pipe and connect it yourself. First, cut the broken pipe, put the joint into one end of the pipe, so that the cutting position at the other end is just flush with the other mouth of the joint, so that it can be straightened, then sent directly to this end, so that the two ends have a certain crossing distance (length), and then taken out and coated with PVC glue.
2. You can buy waterproof glue to repair the water pipe, just wrap it, and then apply mortar waterproofing agent and cement.
If you can't handle it yourself, it is recommended to find a professional company to solve it, which is more professional and faster.
Third, the iron pipe leaks.
1. If the iron water pipe with a diameter of two centimeters leaks, but the iron water pipe is not embroidered, only some parts are damaged, close the main valve of the water pipe and just replace the iron water pipe at that position! Cut off the water pipe at this position, thread it with thread cutting equipment, and connect it in the street!
2. If the iron water pipe with a diameter of two centimeters leaks and the whole water pipe rusts, the main water valve should be closed first, and the corroded water pipe should be replaced in the whole section and tightened at both ends.
3. If the iron water pipe with a diameter of 20 cm leaks, if there is a problem with the pipe body, it needs to be welded, that is, polishing to remove embroidery, and then reinforcing and welding an iron plate that can be attached to the water pipe to repair the leaking place.
4. If there is something wrong with the connector, just replace it directly.
Four, the sink to take over the joint leakage.
If water leakage is found at the nozzle joint of the water tank, it may be that the nut of the faucet is loose, so it can be solved by re-tightening the nut or replacing a new U-shaped gasket.
Five, the sink outlet leakage
If the water outlet of the sink leaks, generally speaking, the axial gasket in the sink is worn and needs to be replaced with a new axial gasket. Loosen the gland bolt with pliers and take it off. Take out the axial gasket with a clamp and replace it with a new axial gasket.
Six, toilet sewer leakage
The leakage of toilet sewer pipe is mainly caused by improper sealing of the original waterproof filler.
Before the pipeline is installed, a hole will be opened in the toilet structural plate, which is larger than the diameter of the drain pipe. If the drain pipe size is DN 1 10, the aperture of the structural plate will be larger than 1 1cm. Therefore, there will be a cavity between the drainage pipe and the structural slab (i.e. the cast-in-place concrete slab). When the cavity filling and sealing treatment is not in place? There will be water leakage.
Waterproof treatment of toilet sewer pipe belongs to detailed structure. In the waterproof construction, it is necessary to embed the seal in this part and increase the reinforcement treatment, so that the waterproof of this part can meet the requirements of different materials for thermal expansion and cold contraction caused by temperature and other factors.
When the toilet drain pipe leaks, it can be repaired or blocked from the water surface. In contrast, the latter is more economical.
