Hallo patryk! Thank you for calling Kings Electric & a/c for your electrical repairs. Today I was called out because you’re having issues with your GFCI in your bathroom. I’m glad to inform you that the old one has been replaced and I installed a new one. Everything is has been tested and it is working correctly. If you have any questions or concerns, please give us a call. I hope you have a great weekend! Ihr Elektrotechniker, Xavier
