Hotel with 2 mains feeds

[Metalmickey]

Hi all,

I've been asked to modify the water supply to a hotel.

The front of the old hotel is connected to the water mains in front of the hotel, and the rear extension backs onto a different street and has an other water main serving the back only.

So can I simply connect the pipework inside to unify the pipework.

The manager wants to avoid being without water in either part of the hotel should one main be cut off for maintenance.

There's a megaflo installed which uses the rear water main.
Thanks for any help

Metalmickey.

do you mean you want to get rid if one supply?

 

[Metalmickey]

No manager wants to keep both and alternate if one supply is being maintained by water company.
As it's a hotel he wants continuous water supply supply if one main is shut down

What if the water board want to do maintenance on, say, the front supply. They turn off a valve somewhere, dig up the road and break into what they thought was an isolated supply, to be met with a flood via the hotel's other supply!

Think you need to ask the water board, and if allowed fit a connection with a valve so that supplies can be separated if necessary.

Ok. So a check valve on both incoming supplies so they can't flood each other.

What about the mega flow. Is this an issue

The only way you can do it is have both supplies connected to a break tank and then pump it out to the hotel

Ok. Thanks for the info.

It's probably worth a phone call to the Water board or relevant authority to get a substantiated ruling on this.

They may give you an approval - with the correct piping / valve set up if they deem it allowable for the type of premises it is.

No time taken for a phonecall and no harm in asking!

I'll throw a spanner in the works. Do u know for sure that both supplies are off different pipes on the street.
