Main Drain Cleaning in Cerritos

By where it shows. A main-line problem presents at the LOWEST fixture in the house, and it presents when you use something else — a shower that fills when the washing machine drains, a toilet that rises when a bath empties. A single blocked fixture that misbehaves only when you use that fixture is a branch.

Because clearing a blockage and removing its cause are different things. A cable through a root mass leaves a hole through the middle of it, and the mass closes again. If the same main has gone twice, the money is better spent finding out why than on a third clearing.

In this order. Lift the strainer and clear what you can reach by hand or with a bent wire, which deals with a surprising proportion. Then a plunger with the overflow blocked off — the step most people skip, and the reason plunging often seems not to work. Then a hand snake fed past the trap, which costs about twenty dollars. If the snake feeds through freely and nothing changes, stop: the blockage is past the trap and into the branch, and that is a machine rather than a tool. Feeding more cable into a line you cannot see is how a $110 job becomes a repair.

On a grease blockage in a metal pipe, hot water genuinely helps, and it is worth two attempts before anything else. It softens the fat coating rather than dissolving it, so it works best combined with running water and dish soap and repeated rather than done once. Two cautions. Boiling water into a plastic waste line can soften or distort the joints — hot from the faucet is the right temperature for modern pipework, not off the stove. And on anything that is not grease it does nothing at all: hair, roots, a foreign object and a collapsed section are not temperature problems, and pouring water onto a full blockage just gives you a sink full of hot water.
