It is a requirement from the health department that all attached hoses have a backflow prevention device. Therefore ALL guests MUST have one installed. If no such device is attached, then Nova will install one and charge your account accordingly.
If you have a dog you MUST clean up after your pet. If you are guilty of leaving you dog droppings, you will be charged a $20 fee for each infraction. However, if it continues you will be asked to leave.
