Drain Cleaning in Pomona: what actually fails

This is where the old pipe actually is. Clay fails at its joints and cast iron scales inward until the bore is half what it was — and both make a caustic cleaner a worse idea here than anywhere else on this map, because there is more surface for it to sit against and less pipe wall to spare.

A much older city north-east of Diamond Bar, established long before the hillside tracts around it and built out over more than a century.

  • Clay or cast iron, established before any method is chosen
  • Scale narrowing the bore on older metal
  • Whether the lateral is shared with another household
  • Nothing jetted at pressure before it has been seen inside

  • A plunger, used properlyBlock the overflow so the pressure goes down the pipe instead of out of the hole, get a real seal, and push rather than pull. On a sink or a tub it outperforms any bottle, and after the first purchase it is free forever.
  • A hand snake, for hairAbout twenty dollars. It reaches the trap and the first few feet beyond it, which is where the commonest bathroom blockage in any house actually sits. Pull the strainer, feed it past the bend, and look at what comes back.
  • Very hot tap water and dish soap, for GREASEThis is what the 'does Dawn really work' question is asking, and on a kitchen line the answer is a qualified yes — grease is the one thing it genuinely shifts. Not boiling water, though: PVC is rated well below it.
  • Not the caustic bottleIt is sulfuric acid or sodium hydroxide, the reaction makes heat, and heat inside a closed pipe softens PVC and the joints holding it together. Worse, when it fails to clear the blockage it stays there, hot, sitting on one spot — and somebody then has to open the trap underneath it.

While you wait

What to do before anybody arrives

  1. Did they ask what you already poured down itThey should, before anything is opened. It is a safety question for whoever is about to dismantle the trap, and a plumber who does not ask is one who has not thought about it.
  2. Did they establish branch or main before quotingOne blocked fixture and one blocked building are different jobs at different prices. The question takes thirty seconds and it decides everything that follows.
  3. Do they know what the pipe is made ofClay, cast iron, ABS or PVC. It decides whether jetting is safe, at what pressure, and whether roots are even a candidate. On this map the answer changes across a county line.
  4. Will they tell you when you do not need themA hand snake solves a great many shower drains. A plumber willing to say so on the phone is giving advice against their own immediate interest, which is the most reliable signal there is.

I already poured drain cleaner down. Does that matter?

Yes, and please say so when you call. If it did not clear the blockage it is still in there, on one spot, and whoever opens the trap meets it first. It is not something we mind — half the country has done it — but we would rather know before than after.

How do I know if it is one drain or the whole house?

Run something else. If one fixture is blocked and the rest of the house drains normally, it is that branch. If using a sink brings something up in the shower, or the lowest fixture in the building backs up, it is the main line.

How often should sewer drains be cleaned?

On sound modern pipe with nothing unusual going down it, never — you clean it when it gives you a reason. The interval only becomes real when there is a cause: a clay lateral with roots at a joint may want clearing every eighteen months to two years, and a line with a belly in it will set its own schedule regardless. If somebody is proposing annual cleaning on a line nobody has looked inside, the honest sequence is a camera first — because an interval is a symptom of a defect, and the defect may be worth fixing instead.

Does Dawn really unclog drains?

For grease, genuinely yes — and for nothing else. Dish soap with very hot tap water breaks down the fat film that coats a kitchen waste, which is the commonest kitchen blockage there is. It will do nothing whatsoever for hair, roots, scale or a dropped object. Two warnings: use hot tap water and not boiling, because PVC is rated well below boiling point and a kettle into a plastic waste is how a joint fails; and if it has not worked twice running, the build-up is further along than the method reaches.
