## Description

Compact, low-profile shower trap designed for installations with limited space. Ideal for small bathrooms and tight areas while maintaining effective drainage.

Review: Great shower trap - Needed to replace our Wirquin shower trap which was a bad design: kept blocking with no way of clearing the parts where the water flowed. This fit the bill to get into a shallow space, and easy to fit (its solvent weld btw... I hadnt realised so adjust some of the compression waste to attach it - you can get a compression version for a few £ more). The trap itself: lift the chrome grate out and there is a tube which forms the wall of the trap. This pulls out and you can clean the inside of any blockages... such a simple but awesome design. Only just fitted but so far it flows far far better than the old Wirquin trap ever did. Will have to see how it holds up to cleaning etc
Review: great trap when space is very limited - After trying about 8 different traps - all sold as 'space-saving' and 'slimline' - yet none of them were - I came across this item. Did the job perfectly. Whoever installed our shower originally did a shoddy job, and used bricks instead of shower legs, and bodged all the plumbing, so the space we had to work in was extremely tight. This fitted perfectly, and with the trap being accessible from the top for easy cleaning, will make things so much easier. So far the flow rate is a vast improvement on the previous trap. Only thing to note - this needs an adapter if you are connecting to 40mm push-fit piping.

## 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.
