A Product Guide for Eliminating Bad Smells in your Drainage Venting System

Choosing the right Air Admittance Valve (AAV) for the drainage ventilation of your project is crucial, whether you have an existing building and you wish to make a retro fit, or it is a new build and you want to specify the correct AAV for the given application – here is our product guide to AAV Solutions.

Problem Solving in Existing Buildings and Specifying for New Builds

Drainage smells due to lack of ventilation in plumbing systems are quite commonplace in existing buildings because of the way they are set up. They usually occur due to the poor design of drainage systems currently in place and the associated lack of ventilation, all in all amounting to bad smells and sewer gas problems.

Whether it is a drainage pipe ventilation issue within a single fixture fitting, such as a toilet, a sink or a shower, or a difference of air pressures within multi-storey buildings, the solution usually draws down to the use of the right Air Admittance Valve (also called a Studor AAV).

Here are common drainage problems, questions and symptoms:

  • What can I do if I have a bad smell from venting pipes and my toilet?
  • My toilet is bubbling and there are fluctuating water levels in it, why?
  • It seems like my toilet or my sink is trying to breathe and it gurgles at the end of the flush or discharge, what causes this?
  • What drainage ventilation system should I use for en-suites and extensions?

All the above situations will be alleviated by the use of Studor AAVs and, in high rise building situations, the use of a Studor P.A.P.A. (Positive Air Pressure Attenuator)

Refer to our AAV solutions to find out how Studor products and services will alleviate your drainage ventilation problems. Here is our Guide to AAVs which will help you specify for certain building types, along with installation guidelines for new builds and retro fits or existing buildings.

For advice on installing the correct combination of AAVs, the Studor System or other associated Studor products, we have an in-house team that has worked on every type of building across the world.
