This is known as an \u2018airlock\u2019. In this case, the containers fit together so perfectly that no air can get in. It is difficult to predict in advance when this might happen, as sometimes they fit together too perfectly.<\/p>\n\n\n\n

There are two ways to solve this problem:<\/p>\n\n\n\n

Option 1.<\/strong> Make use of the Anti-Airlock Clip. If you ordered a Berkey water filter from the summer of 2022 onwards, you will already have received it. This clip is included in the Priming Starter Kit<\/a>, which has been supplied free of charge with a Berkey water filter since the summer of 2022. If you do not have the Priming Starter Kit, you can order the Anti-Airlock Clip separately from us, click here<\/a>.
Place the clip on the rim of the bottom container, with the rounded side facing outwards. Then put the top container back on. This will allow sufficient air to get in, so a vacuum will no longer form and the water will drain out properly.<\/p>\n\n\n\n

Option 2.<\/strong> You could also try rotating the top tray into different positions to see if this improves the fit and allows air to circulate. Another solution is to \u2018roll\u2019 the bottom tray:
\u2013 Carefully remove any Black Berkey filter elements from the system and set the top container aside.
\u2013 If it is already fitted, remove the tap from the lower container.
\u2013 Place a towel on a smooth, hard surface. Place the bottom container on its side on the towel, making sure the towel is held firmly in place.
\u2013 Using both hands, apply gentle pressure to the side of the lower chamber; roll the chamber back and forth across the hard surface. Focus your attention on the upper part of the lower chamber. This will reshape the lower chamber slightly and allow for good airflow between the upper and lower chambers.<\/p>\n\n\n\n

If you decide to use the dice, it may be that the problem isn\u2019t solved after just one go, but in that case you could always have another go.<\/p>","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","faq-categorieen":[1095,1096],"class_list":["post-26666","ufaq","type-ufaq","status-publish","hentry","faq-categorieen-berkey","faq-categorieen-gebruik"],"yoast_head":"\nDe onderste bak van mijn Berkey waterfilter zit helemaal vol met water, maar er komt (bijna) geen water uit het kraantje, hoe kan dit? - Alternatievemiddelen.nl<\/title>\n<meta name=\"description\" content=\"Berkey waterfilters veelgestelde vragen (FAQ) - De onderste bak van mijn Berkey waterfilter zit helemaal vol met water, maar er komt (bijna) geen water uit het kraantje, hoe kan dit?
