Review: It's a compact decent unit - Fits great, works as needed
Review: ... a washing machine and dishwasher plumbed into the same waste pipe, when my dishwasher is off the drain ... - I have a washing machine and dishwasher plumbed into the same waste pipe, when my dishwasher is off the drain stays in the open position, I bought this to stop my washing machine flooding my kitchen, as when the washing machine discharges it’s water, it back flushes into the dishwasher and overflows. I’ve just tested the unit with my dishwasher only, and although I find the unit well constructed, it leaks from where the white plastics connector goes into the clear plastic body (hence the 4stars), this can be easily remedied by unscrewing the unit and either wrapping PTFE tape around the treaded part, or by giving it a wipe with a silicone mastic. Just tested the unit using my washing machine only, as the water discharged the seal worked perfectly no letting water by or leaks. Didn’t need to carry out a test as to when both washing machine and dishwasher washer are on, as mentioned, my dishwasher drain only stays open when it is turned off. I find that this is by far the best unit available for the problem I needed to solved, even with the leak (which at best is a minor inconvenience to fix). I would buy again and recommend to others.

## Questions & Answers

**Q: will this work on my dishwasher discharge pipe as the crockery smells of dirty water.....**
A: I don't think it will as it is designed as an overflow, you need a ubend or trap to stop the drain smell coming back

**Q: can this product be fitted Horzontaly**
A: It would still function in a horizontal configuration as it is spring loaded as opposed to weighted/gravity dependant; but I would say that you need to ensure that there is no potential for grey water to be present on the downstream side of the valve as a quantity would be likely to transfer back across the valve as it operated; possibly resulting in contamination of the water supply. Hope this helps.....

**Q: Hi can this be used with a pressurised hot water cylinder, rather than the current open tundish which is causing headaches for me? Cheers**
A: I think regs require the tundish is open the cylinder is pressurised and would be very dangerous if the pressure could not escape though the pipe if it got blocked at the other end

**Q: Is this suitable for use between d1 and d2 pipes on a unvented cylinder installation?**
A: You need the HOTUN device for hot water unvented discharge.
