Rated 5 out of 5 by from Long story short. New house build. Thought roof was leaking. But soil pipe was lashed in with wrong fittings to breather. This product cured the problem. 100% happy.

Rated 5 out of 5 by from Neat and effective Purchased to replace an old one which was allowing sewer smells into the roof space. Push fit- so very quick to fit and smell now gone. See no reason why we shouldn’t have an odour free loft for the foreseeable future.Used the click and collect system which works brilliantly. Only 4 stars for reliability as only fitted it yesterday!

Rated 5 out of 5 by from Best air admittance valve ever Bought as replacing roof and didn’t want unsightly and potentially leaky holes in roof for soil pipe. Cut pipe below roof Level in loft and slotted valve on top in seconds. Very simple, fit and forget, a bit more expensive then other brands/stores but chosen for the (hopefully) reliability of FloPlast. Screwfix oxford as good as usual.
