1.A strainer is recommended to be installed ahead of the backflow preventer to prevent the fouling of the check assembly and resulting spillage from the valve during repressurization.
2.This device should be installed at the furthermost downstream end of the supply pipe or fixture where temporary spillage due to critical flow pressure conditions can be discharged harmlessly.
5.So I've got pretty much all of these rows now are in East Town and a little bit of spillage here, but basically I've got East Town in the front; I can't see the balcony.
