A brief article about waterproofing as told by a top contractor in Philadelphia
As a general rule in Philadelphia, and across the Northeast, when it comes to waterproofing, keep garden hose use from stealing too much water pressure from house fixtures. Take them from the cold water main close as you can to the water heater. Don't use any end of main hose takeoffs. And never take them from the 1/2 branches serving fixtures. If a run serves two sillcocks, you can make it from 3/4 tubing, but reduce to 1/2 where the branches separate. Of course, if you soften your water, all sillcock runs should exit before the softener.
Plan your system in the direction of water flow, locating the fixtures and then the pipes necessary to serve them. Space hot and cold lines about 6' apart. Never cross connect the water supply system to the drain waste-vent system or to any other source of contamination as part of installing waterproofing. We recommend simply sketching out the system, not necessarily to scale. Show all fixtures and appliances, all pipes and fittings, labeling them.
