Anti-vac valve seals for all Breville dual boiler machines - 900 through to 990.
The anti-vac valve on the steam boiler is very often overlooked and we've seen MANY of these machines with leaks here. The seal around the plunger goes brittle over time and this allows pressure to vent from your steam boiler, which makes it have to kick the element on again to top it up more frequently. If the leak gets bad enough, it can lead to much more scale build-up in your steam boiler due to it heating more often than it should. More scale = more chance of compromising the boiler element which = a boiler replacement which is very expensive! If you already have the machine open, you might as well use an 18mm spanner/socket to remove the anti-vac, give it a quick bath in descale solution and replace the seals.
Some symptoms of of a leaky anti-vac valve are:
- You notice your steam boiler topping more often, but there's no leak in the machine from either the boiler or the hydraulics
- The drip tray seems to always have clean water in it
- There's a hissing sound or steam coming out from the left-hand side of the drip tray
- There's often water beneath the drip tray - this comes from steam eventually condensing on the roof of the drip tray area and ends up trickling down the sides and under your drip tray.
Kit includes:
- 1 x silicone seal for the anti-vac plunger
- 1 x silicone seal for the anti-vac housing nut
If you notice any of these symptoms coming from the right-hand side of your drip tray, chances are that you might have a descale drain valve leak. We have a seal kit for those right here: https://www.ebay.com.au/itm/235647039807

**A quick disclaimer**
I love free things, we all do, and that's why I offer free postage on some of my listings. I make it a habit to send your orders through the post office directly, rather than dropping it into a Post Box where they can sometimes get stuck in the mail bag. Please understand however that if you choose the free shipping option, there is no tracking number. If you opt for free postage and your order doesn't arrive, I can't be held liable. It's rare, but it can happen.
I take photos of all orders before I ship them out and am happy to send you yours as proof.
To avoid this, I recommend using either the standard trackable mail option or even the Express post option if you need your order in a hurry. They might not be free, but they're trackable.
Thanks for your support and understanding,
