Question

Water flow from the over head tank to our bathroom geyzer in the first floor is not fine. Sometimes it just stops or it comes like a trickle. I have checked the pipes and the connection is all fine. I believe there might be some pressure and vaccum related issue here which is preventing the water from the geyzer from flowing through the tap. Any advice or checks on these lines will be appreciated.
