The first thing to work out is whether you have one blocked fixture or a blocked main line, because they are different jobs with different urgency. In Tempe's older core the answer is often decided by the age of the pipe rather than by what went down it.
One fixture, or the main
If a single sink or shower is slow and everything else drains normally, the blockage is in that fixture's branch. It is contained, it is not urgent, and it will usually wait for daytime rates.
If the lowest drains in the house are backing up, if flushing a toilet makes a shower gurgle or fill, or if more than one fixture is affected at once, the blockage is in the main line. Everything the house sends down has nowhere to go and comes back at the lowest opening. Stop running water anywhere until someone looks at it.
What actually blocks a line in Tempe
Grease is the common one and it is cumulative. Fat poured down a drain cools, coats the pipe, and narrows it over months until something ordinary finally bridges it.
In the older core, where the drains are cast iron, the pipe itself is often part of the problem. Cast iron of that era scales, cracks at the joints, and takes root intrusion where joints have opened. A line that backs up at the same time each year is usually telling you about roots rather than about what you put down it.
So-called flushable wipes are the third cause and they are not flushable in any sense that matters. They do not break down and they catch on whatever is already there.
Cabling clears it. A camera tells you why.
A cable clears the symptom and tells you nothing about the cause. On older Tempe housing that distinction decides whether you are booking this job once or three times.
Ask for a camera inspection on any main line blockage in a pre-1970 house, and ask to see the footage. It is the difference between roots you will see again in six months, grease you will see again in two years, and a bellied or collapsed section that needs digging.
Do not pour chemicals into a backed-up main
Caustic drain cleaners are designed for a small blockage close to a fixture. In a main line that is already standing full they do nothing except make the water dangerous for whoever has to put a hand in it.
If the water coming back up is not clean, treat it as a health problem first. Keep people and pets out of the room and off the wet flooring.
Common questions
How do I know if it is the main line?
More than one fixture at once, the lowest drains in the house backing up, or a toilet flush that makes a shower gurgle. One slow fixture with everything else fine is a branch problem.
Will cabling fix it permanently?
It clears the blockage. Whether it comes back depends on the cause, which is what a camera is for. Roots return in months, grease in years, and a collapsed section does not clear at all.
What does drain cleaning cost?
Roughly $150 to $350 for one fixture and $250 to $600 for main line cabling in this market. Those are ranges from published local pricing, not our prices.
Can I use a chemical cleaner first?
Not on a main line that is already backed up. It sits in standing water doing nothing and it makes the job hazardous for the person who has to clear it.

What emergency plumbing costs in the Phoenix metro
Prices surveyed 2026-09-12
These are market ranges taken from what local contractors publish, not quotes and not our prices. We set no prices and take no cut of the repair. Reaching the pipe is usually what costs, not the pipe.
| Job | Typical range | What drives it |
|---|---|---|
| Emergency or after-hours diagnostic call | $50 to $150 | Often credited against the repair. Ask whether it is, and get the number before a truck rolls. |
| Drain cleaning, one fixture | $150 to $350 | A branch blockage close to the fixture. Rises sharply if the main line is involved. |
| Main line cabling | $250 to $600 | Clears the symptom. Ask for a camera inspection before paying for it twice. |
| Water heater replacement | $1,200 to $2,500 | Tank units. An element or a thermostat is a fraction of this, so ask which failed. |
| Burst pipe or slab leak, spot repair | $500 to $2,000 | Access drives the number. The same break in a wall or under a slab costs multiples of one in an attic. |
| Whole home repipe | $4,000 to $12,000 | Quoted when spot repairs stop being economic on failing galvanized or polybutylene. |
Ask for the diagnostic fee, whether it is credited against the repair, and whether drying and reinstatement are included. Most plumbers fix the pipe and leave the wall open.
Bars are on a logarithmic scale from $50 to $12,000, so the smallest and the largest job on this table are both readable on the same row.
