    used this as part of a special dog toilet I built in the garden so it is used vertically. Works fine as expected. Would use these for all my new Wc's, especially when someone told me their story of a squirrel that came up the loo!

    s. · 26 May 2023

    Bought two of these in an attempt to stop the smell from the main sewer wafting through the house from time to time from the kitchen and downstairs bathroom outlets. They were easy to fit and I checked the water was flowing before refitting the drain cover. The doors automatically open when the water pressure builds up behind them. It’s been a few days now and I can honestly say there have been no odours whatsoever. Wish I’d bought some of these ages ago.

    Al momento sembra troppo bello per essere vero.

    P.G. · 15 October 2019

    Preso per disperazione causa continui riflussi di acque nere. Installato dal pozzetto d'ispezione. Facilissimo da inserire (e questo mi ha stupito) per misure standard. Per sicurezza ho siliconato tutto attorno ma sembrava stabile anche senza. Posizionato in orizzontale, funziona perfettamente. Monitorerò comunque nelle prossime settimane.

    La rapidez y la calidad

    Avis sur le produit

    g.n. · 11 October 2024

    J’ai utilisé ce clapet pour éviter des mauvaises odeurs dans la douche. Résultat concluant. Seul bémol, les dimensions du clapet ne correspondent pas aux dimensions sur le site. 110 mm au lieu de 120 mm. Donc il a fallu que je bricole une bague.
