Olde Boston’s Restaurant and Pub has been forced to close after extensive water damage was discovered in the restaurant early Saturday morning, according to Jim Bird, owner of the establishment.

The restaurant, located at 809 Central Ave., is housed in the Boston Centre. That building is water cooled and heated.

“It uses a water tower,” Bird said. “It has a boiler for heat.”

Bird said large hoses that keep the water circulating came undone on Friday night.

“We didn’t realize it had come undone until the cleaning crew got there at about 4 a.m.,” Bird said on Saturday.

The full extent of the damage isn’t yet known, but Bird said it’s enough that the restaurant has to close.

He said the business is likely to be closed for a minimum of about two weeks.

Bird is optimistic that the restaurant will be able to open sooner rather than later, but said that could be dependent on the parts needed to make repairs.

“Our contractors are telling us availability of product is not very good right now,” Bird said. “They are struggling to get things in. It could take several weeks to get certain products. Hopefully it’s not that long and we can get going.”

A full assessment of the damage will be conducted today.
