Review: Perfect for dishwasher & washing machine - Moved into a new house which only had pipework under the sink for a single appliance waste pipe. Replaced with this as we have both a dishwasher and a washing machine. Very easy to install, universal fittings so everything fits perfectly. No leaks and no problems. Perfect for the job!
Review: Easy to fit and no leaks - We wanted to plumb in our new dishwasher and need an extra water outlet on our sink trap. Decided instead of trying to add pieces to the existing piping to order this. So easy to fit took minutes and replaced the other pipping as why not use all the new fittings. No leaks and good quality fittings, very pleased.

## Questions & Answers

**Q: When should I use an anti-syphon or resealing trap?**
A: Generally, the waste pipe or discharge pipe from an appliance is beyond the limitations of an unvented waste pipe. Usually more critical on the basin and bidet Wastes.

**Q: What is the difference between an anti-syphon trap and a re-sealing trap?**
A: A re-sealing is designed to allow air to pass through the water seal under negative pressure but will retain sufficient water. An anti siphon trap has a small mechanical valve which opens under negative pressure.

**Q: Why does water not run away in my shower?**
A: If it is not due to the obvious reason of a blockage caused by a buildup of debris, the problem could be due to back pressure within the discharge pipe.

**Q: What is the maximum thickness of bath that your bath fillers can be installed on?**
A: The maximum thickness of the bath is 20mm and unfortunately, we do not make an extension ferrule to extend that length.
