## Description

Waterless waste trap for baths. HepvO is different to traditional water traps as it uses a soft silicone rubber membrane to create a seal, instead of “trapped” water. HepvO can be installed vertically or horizontally.

Review: Does a good job - Eliminates smells all good
Review: Easy to fit in shallow gap below bath - excellent product and easy to fit to bath. Description says tested resistant to chemicals like paint thinner. Others state they cannot have drain blocker put down......time will tell if this as his as it states . Only disappointment and hence 4stars only was although I was aware, the knuckle connector is not included in the pack and had to be purchased separately from Toolstation for £8

- Can be installed vertically or horizontally
- The compression end will fit both solvent weld and pushfit pipe

## Questions & Answers

**Q: Is 40mm the width of the pipe? (not the pipe plus screw fitting)**
A: Mr P,

40mm (1.5") is the diameter of the pipe that this fits, such as is used for baths etc.  There is a smaller size which is 32mm (1.25") typically for the pipes used for hand basins.

Regards,  lim

**Q: are these suitanle for outdoor use**
A: yes of course, it is like any other conventional syphons except that it can also be installed horizontally and vertically.Hope this answers your question this time.

**Q: Does this work fine with a washing machine without restricting flow, and do they need replacing every x nimber of years or do they work indefinitely?**
A: It'll work fine on a wasing machine as it's wider bore than the outlet hose. Even though guaranteed for 3 years, we've had one for 10+ without problems.

**Q: What is the length of this thanks**
A: PM,

The length of the Hepvo waste valve as shown in the photograph is 188mm, but be aware that if it is used between two pipes the 'running adaptor' will increase overall length to 208mm.  For all the information on Hepvo, try their download site:  <https://www.wavin.com/en-gb/Downloads?systems=S027>. There is a useful brochure with lots of pictures, applications and dimensions.

### ⭐⭐⭐⭐⭐ Top notch.
*by A***R on 18 June 2024*

Cured to sewer smell coming from the bath. We don’t use the bath that often so the conventional p trap would dry out and let the smell in. This ingenious device has cured all that.
