Why is drain backup water treated as contaminated?
Because it has been through the drain system and carries waste. Contaminated water can carry bacteria and other organisms, so it is handled with protective equipment and its porous materials are usually removed.
Clean water from a supply line changes category if it stands, touches other materials or mixes with waste. A backup from a drain starts in the contaminated category because it has come from the sewer or the drain system. Porous materials such as carpet pad, unfinished wood and insulation take in contaminated water and cannot be fully sanitised, so they are removed. Hard surfaces can be cleaned, and the decision is made room by room on site, with the category written down for each.
Can a backup be stopped during a storm?
Sometimes, by closing the fixture the water is coming through and keeping the water out of the room. A floor drain that is backing up during a storm is harder to stop, and the crew works to contain the water rather than to stop the source.
A homeowner can close a toilet lid, a shower drain or a sink plug to stop water coming through those fixtures. A floor drain is harder, because the water rises from the main drain line, and stopping it depends on the drain system outside the house. If water is rising in a floor drain during a storm, keep the room closed, move items out of the water and call the line. The crew works to keep the water contained while the source clears.
What gear does the crew use?
Protective clothing, gloves, eye protection and respiratory protection suited to the contamination, plus equipment dedicated to the wet area so it does not carry contamination into clean rooms.
The protective equipment is chosen for the category of water and the work being done. The crew uses it from the first step, not only once the water is removed. Equipment that has touched contaminated water is kept in the wet area or cleaned before it is used elsewhere, and the record notes which tools were used in which rooms.
What should a homeowner do after a backup?
Keep people and pets out of the wet area, do not run a household vacuum or fan through the water, photograph the water and the drain, and call the line.
Contaminated water should not be touched with bare hands or cleaned with household equipment, because the equipment can spread the contamination into the rest of the house. The homeowner should photograph the water, the drain and the rooms before anything is removed, and should note the time the water was seen. The line is answered 24/7 on (833) 490-5225, and the caller is asked the questions the local company needs before any work is agreed.
Does the drain need repair after the cleanup?
Often, yes. The cleanup removes the water and the contamination, and the drain system is repaired by a licensed plumber the homeowner hires, because a backup that recurs will keep bringing water back.
A drain that backs up again within a day of being cleared needs a plumber to find the cause, which may be a blockage, a broken line or a failure of the backflow device if one is fitted. The crew's record of the backup, its level and the rooms reached is handed to the plumber so the repair can begin from the right place. The repair itself is not part of the water work.
