How to Install a Foundation Drain Does it really make a difference whether the perforated drain pipe goes on top of the footing or beside the footingWhy weeping tile is installed around your foundation. Weeping tile has been installed to drain water that pools at the base of foundations for the last 80 years or so. Drain tiles function is to remove water from around the exterior of the foundation, and most local building codes now require the installation of drain tile during. Dampness in basements or crawl spaces can lead to the development of unpleasant odors, problematic mold and even structural problems. One solution to moisture. Swimming Pool Check Valves, Use, Selection, Installation. A check valve is a one way flow valve, with a purpose to keep water from flowing backwards or to prevent cycling of water in solar systems or bypass loops. Check valves are used in pool, spa and fountain plumbing to keep water flowing in only one direction. When are Pool Check Valves Used The purpose of a check valve is to force water in a pipe to flow in one direction only, and also to prevent gravity draining of water in the filter, pump and pipes, when the pump shuts off. They are also used to keep raised spas, fountains or solar heaters full of water, when the pump shuts off, again to prevent gravity draining.

Raised Pool Pumps. The most common use for a check valve is to hold the water in the pump when the motor shuts off. As such, a common location for a check valve is on the incoming suction pipe, in front of the filter pump. For best results with pump priming, especially for pumps lifting more than 2. This allows not only a full basket, but also a full pipe of water. If space is not available for a check valve on the horizontal pipe that comes into the pump, check valves can be installed on the vertical suction lines, or the skimmer and main drain pipes. When doing so however, you will need to install check valves on all vertical suction pipes, unless one pipe normally has a closed valve, like a spa drain pipe. For pools that winterize their system during winter, placing check valves on vertical suction lines prevents air from being blown backwards through the skimmer and main drain pipes. There also is the concern of water being trapped on top of a vertically mounted check valve. Installing PVC Unions directly beneath a vertical check valve will overcome the problem, and allow full winterization of the suction lines. Another option is to move the pump further back from the incoming valves, andor reconfigure the suction manifold, to add more horizontal pipe space for mounting a single check valve, between the pump and any suction line valves. Pump check valves help inground pool pumps to catch prime quickly, by keeping the water in the pump and filter, when the pump shuts off. This ensures fast pump priming for long motor life, and also prevents pool filters from back flowing DE or dirt to the pool, when the pump is off. Check valves are not normally used on aboveground pools, which have their equipment located below water level, in what is called flooded suction. Solar Pool Heaters. Solar pool heater panels that are roof mounted may use check valves on the supply and return pipes. A check valve placed on the pipe that leads to the solar panels will prevent drain down of the solar system, when the pump shuts off. A second check valve may be placed on the pipe that returns from the solar system, to prevent water from cycling backwards through the solar panels, when the solar system is turned off. For pools that winterize their system during winter, you can place PVC unions on either side of the check valves to allow for system drain down andor blowing out the solar panels with air more confidently. New style check valves from Jandy, Pentair and Waterway are serviceable, and can be opened to allow for solar system drain down, and to be sure no water is trapped on top of the flapper, after winterizing. Chlorinators. Pool chlorinators can potentially damage a pool heater or filter, if they are installed too close to other equipment. A check valve can be installed just before the in line chlorinator or just before an off line chlorinator injection point, to keep high concentrations of chlorine from backing up into heaters, filters or other nearby pool equipment. Raised Spas. Remember that water seeks its own level, and when a spa, fountain or water feature is placed at a higher level than the pool water, it will naturally gravity drain into the pool, when the pump shuts off. Check valves are used on spa return lines, andor spa overflow lines, to keep attached spas on shared systems from losing gravity draining when the pump shuts off. Similarly, check valves can also be used for wall fountains, deck jets and waterfalls, to prevent draining when they are not being used. Spa Blowers. For pools with attached spas, a blower line is often attached to add forced air into the spa jets. Many builders place the blower on top of a tall pipe, several feet above the pump level, to keep water from entering the blower motor. As added insurance, may builders install a check valve on the blower pipe, to keep water from backing into the blower motor. How To Install Apk Files On Windows Phone there. Ozonators. Ozonators use small ball check valves on the ozone feed tube that carries the ozone gas to the injection fitting another type of small ball check valve. Manufacturers recommend regular replacement of the ozone tubing and check valve, to keep the gas flowing in one direction only, and to prevent water from backing into the ozone production chamber. Spa Overflow Lines. For pools with attached spas with a controller, a spa overflow line or spa make up line bypass line is often used to send enough filtered water to the spa returns to keep it clean and circulated, as the spa drain and spa return valves are normally closed. When the valves are opened to Spa Mode, a check valve is used on the spa over flow line to keep water from looping backwards through the overflow pipe. Types of Pool Check Valves. In regards to internal operation, there are three basic types, swing check valves, spring check valves and ball check valves. Swing check valves have a flapper door or diverter on a hinge that swings closed when the pump is off, and swings open, in one direction only, when the pump is on and pushing water through the valve. Ball check valves utilize a round ball inside that rolls closed when not under pressure, and rolls open with the water flow. Spring check valves have a ball cone or disk diverter and a compression spring. As water flow increases, the spring is compressed, separating the disk or cone from the housing and allowing water flow. When the pump is off, or lower than the required cracking pressure of 1 to 3 lbs psi, the spring seals the diverter into the housing, stopping water flow. Swing check valves are generally preferred over spring valves in pool and spa plumbing, because they dont clog as easily, and a steel spring can deteriorate in harsh water conditions. And the pressure required to open a spring check valve adds pressure to the overall system. The preferred pool and spa check valve is the type pioneered by Jandy, an ABS swing check valve with a clear, removable lid for inspection, repair or winterization. They are available in a straight flow thru 1. Jandy check valves are available to fit pipe sizes of 1. Waterway has redesigned the original Jandy check valve into their own version, the Waterway Truseal Serviceable check valve, by securing the lid with a quick opening lock ring, rather than the 8 screws used on Jandy check valves. Pentair also has a line of inline check valves available, based on the Pac Fab Compool line, another Jandy valve redesign, and also continues to make Ortega spring loaded check valves. Valterra has a SwingSpring Combination check valve that can be installed in any position. Clear housing, union connections and a low 0.
