The job of the condensate pipe is to transport acidic water, caused by waste gas, away from the boiler. This usually runs outside into a drain, because of its location it faces the risk of freezing.
If your condensate pipe has frozen, it will need to be thawed out. If you don't feel comfortable doing this yourself, call out a registered engineer.
Your boiler gauge should show that the boiler pressure is between 1.0 and 2.0. If the pressure drops below 1.0, then you'll need to repressurise it. Follow our guide to low boiler pressure to resolve the issue.
When you see water coming from the bottom of your boiler, the most common cause is a broken internal component, normally a pump seal or pressure valve. To determine the cause, it's always best to get a Gas Safe registered engineer on the case.
