This process is repeated. After the rod has been pulled through the drain several times, it is advisable to clean the drain further with a ball of barbed wire or a chain. Flushing, as described below would also be advisable. Sewer rods are inserted into the drain in a similar manner to the corkscrew-end rod. The rods may be used plain or with various tools on the end such as scoops, hooks and augers.
Special drain flushing equipment is available.
The nature of the deposit in the drain governs the success of the procedure. To flush and clean a drain, a reasonable supply of water must be available. One method to consider is using an irrigation system. A large volume of flow rather than high pressure should be used. The effect of jetting with high pressure will not be felt any great distance down the drain.
