Strange smell?

grahampb

Mm.......... not really sure where to start!

For the past 10 days we have had a really strange smell coming from the dining room floor. Next to the dining room is a downsatairs bathroom that was added as a extension, and the smell seems to coming from the gap between the skirting board and the floor, the smell sometimes comes up in the bathroom but not very often. The sewer pipe runs directly outside the dining room,( in conservatory) but is covered by laminate flooring. We recently purchased a powerplate machine (vibration training machine), which sits directly above the sewer pipe in the conservatory. I can only describe the smell as very sour and quite overpouring, kit is not constant but flares up at ivarious intervals. We have thoughly cleaned everywher but it seems to have made no difference.

Hope someone can advised.

Hi

Find the inspection chamber nearest the house.(manhole) Is it blocked? If not then:
Test to see if it's yours by flushing the wc.
If it is lob one of these it it and put the lid back.

See what happens!!

Have you got an internal soil stack pipe? Sometimes they are not vented to the outside above the roof height so to get around this they have an internal stack with a special cap called an AAV (Air Admittance Valve)that contains an rubber seal. If its old the rubber can perish and bend and therefore not sit flat and this allows smells in. You can buy replacement AAV's for £5 or £6 from most plumbers merchants and they are easy as you change the whole cap. Link below will explain a little more. Hope this helps.

Maybe a dead mouse or rat ?

We've had a few nasty smeels under wood floors sometimes at work
