Clogged hot water pipes in the bathroom wall result in a small flow of water that prevents the water

(1) PP-R hot melt pipe, in the construction of excessive heating, will lead to the necking of the pipe head connection during the connection, resulting in blockage, so that the water flow is too small.

1) This matter cannot be dredged, so it can only be solved by knocking on the wall and changing the pipe.

2) During construction, it may also get into the pipeline, such as cement slag or bricks.

2) The pipe is too thin, and there is a 90-degree elbow, and there is no suitable tool for dredging, so you can only knock on the wall and change the pipe.

The relatively long pipe can not be dredged, can only disconnect the pipe suspected of being blocked, and re-pull the pipe, now pulling the PVC pipe is very simple, the cost is low, the construction period is short, the effect is good, and the renovation of the old man's house does not break the wall is basically this method.

In addition, it is necessary to carefully check the faucet, many of the reasons for small water are caused by the rust of the ball valve inside the faucet and cannot be rotated. If the faucet of the sink has a filter, it should also be cleaned to rule out the cause of the clogged faucet.

This situation is generally not easy to dredge, if you don't want to knock on the bricks, the best way is to go to the open pipe.

You buy a better hot water pipe, a white one.
