After the installation of PVC lay flat hose, water test will be carried out. This is to ensure the normal use of PVC lay flat hose, so that it has a better effect in use. It is the product application information that we should focus on.
In the water test of PVC lay flat hose, the control gate valve should be opened first, the whole pipeline should be filled and washed with water, all the debris in the pipeline should be removed, and then the tail of pipelines at all levels should be blocked with plugs, so that the test can be carried out. The second is to supply water according to the corresponding pressure, adjust the gate valves and check whether the joints and pipes are leaking or not. If there is a fault, it should be repaired in time.
After normal water test, Backfilling Pipeline should be carried out in different layers. Fine sand must be used to close the pipeline. At the same time, attention should be paid to the influence of season to ensure the normal use of PVC lay flat hose and make it more popular with users.
