Ask the Builder: Fixing sewer fuel mysteries

I’ve all the time beloved doing plumbing work as a result of it’s a real three-dimensional puzzle.

I’ve been a grasp plumber since 1981, and I all the time say if in case you have a daughter, son or grandchild who needs to have a rewarding profession that gives important revenue, level them to a commerce faculty that teaches this craft.

Immediately I need to speak about sewer fuel. It’s very important that plumbing drain pipes, in addition to the vents that hook up with them, be put in accurately so sewer fuel by no means enters your property. Each week, I resolve sewer fuel issues over the telephone with householders. In truth, on the day earlier than I wrote this column I solved a vexing downside for a New Mexico home-owner simply hours earlier than he was anticipating home company.

Sewer fuel will be present in septic tanks, metropolis sewers and the drain pipes in your house. It smells horrible. It’s brought on by the decomposition of bodily waste and rotting meals that you just ship down your drain pipes. It’s poisonous and might trigger extreme sickness should you’re uncovered to sufficient of it for lengthy durations of time.

Persons are additionally studying…

Simply two years in the past a person employed me to return to his house to resolve a sewer fuel difficulty. His spouse was ailing and no physician might work out the trigger. Inside minutes, I related her struggling to the leaking sewer fuel. I discovered that they’d put in a brand new tile flooring on high of an current one in a powder room adjoining to the place his spouse sat and watched TV.

After the brand new flooring had been put in, the tile setter or plumber failed to put in an additional wax ring to account for the truth that the bathroom now sat a half-inch larger than it had earlier than. Sewer fuel was leaking from the bottom of the bathroom. As quickly as two wax rings had been put in on high of one another on the bathroom flange and the bathroom was reset, the sewer fuel stopped getting into the house.

It’s very important to know that the plumbing pipes in your house work just like the blood vessels in your physique. When all is properly in your physique, your blood stays contained in the blood vessels. In the event you reduce your self or if a vessel breaks below stress, blood leaks out. The identical is true for the pipes in your house. When all is properly, the liquids, solids and sewer fuel keep within the pipes.

But when a pipe cracks or has a gap drilled in it, or if a entice below a fixture dries out, you’ll have hassle. Dried-out p-traps below sinks, showers and flooring drains are the commonest supply of sewer fuel. The p-trap incorporates a curved pipe, most frequently a U form, that traps water on the backside of the curve, and this acts as a barrier to fuel and vermin getting into your property.

Two years in the past I did a telephone session with a person that owned a condominium in a high-rise constructing in Monaco. He had a horrible sewer fuel downside. It turned out the fuel was leaking from a number of different models above and beneath his condominium!

Most of the condominium homeowners solely keep of their models for a number of months out of a yr, and whereas they’re gone, water evaporates from the traps below all of the fixtures and from the bathroom bowls. As soon as the water seal within the traps is damaged, the sewer fuel wafts into the unit after which enters the tall plumbing shaft the place all of the pipes go all the way down to the road. The sewer fuel within the tall shaft was moving into the person’s condominium.

I had him contact the condominium upkeep supervisor. He used his grasp key and went into every vacant condominium. He then ran water in all of the fixtures and flushed all of the bathrooms. Inside hours, the sewer fuel downside in the complete constructing stopped.

Wind may trigger an issue. That plumbing pipe up in your roof works within the reverse manner chimneys do. Chimneys are designed to eliminate smoke from a hearth or furnace. Plumbing vent pipes draw contemporary air down into the pipes in your house every time you run water in a sink or bathe or flush a bathroom.

A yr in the past I wrote a easy booklet about sewer fuel. It explains how plumbing programs work. When you’ve got a sewer fuel downside, the e book asks you a collection of questions to assist slim down the potential sources. Inside a couple of minutes, you’ll possible be capable of work out the issue by yourself. If not, I’m out there to speak on the telephone.
