Swimming Pool Problems and Solutions. Air Relief Valve aka Air Bleeder used on top of the filter, this device is used to let the air escape and allow the tank to fill with water. Its critical to open the air bleeder before restarting the motor. The force of the water can compress the air and cause excessive pressure which can damage the equipment. Common Problems Solutions Problem The air valve wont open. Solution The unit needs to be disassembled with tools and lubricated. Problem Water keeps squirting out even when closed. Solution The rubber seal ring on the inside of the unit is damaged or missing and needs replacement. Problem The valve is opening and nothing comes out. Solution The passage is clogged with debris and needs to be disassembled and unclogged. Backwash the process of running water through a filter in the reverse direction to flush the filter of debris and contaminents, freeing up the filter to be less restricted so the water can pass through the filter more efficiently, collecting more debris. Common Problems Solutions Problem The water flow flowrate didnt increase after the backwash, and the tanks pressure is still higher than usual. Solution More backwashing is needed. Pool Plaster Crack Hollow Sound' title='Pool Plaster Crack Hollow Sound' />Be sure that the hair and lint strainer is always cleaned before backwashing. Problem No water is coming out of the pipe. Solution The pump must be primed. Cartridge the element in a filter, covered with pleats of fabric, to strain debris and contaminants from the water passing through it. Common Problems Solutions Problem The filter becomes clogged and requires cleaning. Solution Remove the filter element, replace with the previously cleaned set, and rinse dirty elements with pressure or soak in a degreaser TSP. Problem The filter fabric rips, and allows dirty water to pass through. Solution The damaged filter needs replacement. Caulking material used in a joint to create a waterproof seal. This Shona language page contains a searchable EnglishShona dictionary for converting common English words to Shona. Athletic Traffic Marking Paints Zone Marking Traffic Paint Latex Latex Traffic Zone Marking Paint is a glare free paint to be used for designating all types of. Common Problems Solutions Problem Splitting from the sides of the joint, holes where it was applied too thin. This allow water to seep into the joint. Solution Remove old caulk, clean joint, tape both sides of joint, apply caulk compound, strike to smooth finish and pull tape. Correct any imperfections by hand with a release agent and allow to dry. Centrifugal Force the outward force created by an object in circular motion. The force that is created by water pumps to move water. Chlorinator a mechanical device or pump that delivers chlorine to a body of water. Common Problems Solutions Problem The pump tube wears out. Solution Replace the pump tube assembly. Problem The strainer is clogged. Solution Replace or clean the strainer. Problem The injection fitting is clogged. Solution Replace or clean the injector. Problem The tubing is cracked or split, allowing air to disrupt suction force or the chlorine to leak. Solution Search for the leak, possibly shorten the tubing to eliminate the leak which is common at the ends or replace all tubing. Circulation System the combination of pipes, pump, filter, and other components through which water flows. Common Problems Solutions Problem The filter is clogged. Solution Backwash or change cartridges. Problem The strainer is clogged. Solution Clean the strainer a must before each backwash. Problem Loss of prime. Solution Familiarize yourself with each systems needs. Depending on system design and equipment, there will be different procedures. Refer to your pool chart. Startups Accelerator Program Pdf. Coping the cap stone on the edge of a pool or spa mounted on the bond beam. Common Problems Solutions Problem Cracks. Answer A crack can be repaired with mortar or epoxy. This is a temporary repair to ensure a smooth, safe surface. If in very poor condition, replacement is required. Problem Hollow or delaminating at bonding surface. Solution Re set the stone by removing stone cleaning surfaces and reapplying in a fresh mortar bed. Engenharia De Software Pressman Pdf'>Engenharia De Software Pressman Pdf. You can also replace the stone. Discharge the flow of water out of a pipe or port. Common Problems Solutions Problem Water leaks. Solution The PVC piping and fittings must be removed and replaced to reseal the threaded discharge, this commonly is a repair that is conducted by an experienced repair technician. If the discharge has a bolted flange, a rubber gasket makes the seal, and it may just need tightening. Effluent the water discharging from a pipe or equipment. Erosion System a type of chemical feeder in which tablet sanitizer is slowly dissolved by constant flow of water through the device. Common Problems Solutions Problem Chemical fumes. Solution Wear safety gear when checking the system. Try to add chemicals to an empty feeder only. Never add the residual dust from the container. Vile Darkness 4E Pdf. Problem Slow addition of chemical. Answer A supplemental chemical, such as granular chlorine, may be needed for superchlorination. Filter Run the time between cleanings, expressed as the total running time of the system, also called the filter cycle. Common Problems Solutions Problem Inconsistent or irregular cleaning can result in turbid water. Awareness of the filter run will allow the prediction of cleaning frequency. Solution Consistent record keeping, including change in flowrates, tank pressure, and pressure differential will reveal the patterns of the filter run. Flow Meter a device for measuring the rate of water passing through a given pipe, expressed in gallons per minute gpm. Common Problems Solutions Problem The float becomes stuck, indicating an inaccurate reading. Solution Lightly tap the top of the flowmeter to vibrate the float and dislodge it. Be careful not to exert too much force on the unit, as its plastic and will break. Problem The painted numerals on the flowmeter become faded. Solution Replace all flowmeters which have faded numerals to avoid rule violation. Flow Rate the volume of water passing a given point in a given time, expressed in gallons per minute gpm. Common Problems Solutions Problem Flow rate is lower than the requirement. Solution A low flow rate will be unacceptable to county inspectors, and indicative of a pump or filter restriction, or an improperly sized pump. High flow rates are acceptable as long as the rate does not exceed the filter systems capacity. Gate Valve a valve that restricts water flow by raising and lowering a disc across the diameter of the pipe by means of a worm drive. Common Problems Solutions Problem Stripped threads at the worm drive, the round handle will keep spinning without moving the disc. The problem is not visible. Solution Damaged valves need repair or replacement. Gauge refers to a measuring device, as in pressure gauge. Typically 0 6. 0 p. Used to measure tank pressure, influent pressure, and effluent pressure on filtration systems. Common Problems Solutions Problem Some gauges are made with metal components which do not last in pump rooms due to the chemical fumes accelerating the deterioration. Solution Replace any gauge that does not zero out when the system is off. Replace when needles are damaged or the unit fills with water. Gunite a dry mixture of sand and cement that is mixed with water at the nozzle and sprayed onto contoured and supported surfaces to build a pool or spa, creating the shell of the pool. Common Problems Solutions Problem In situations where the shell has not properly been waterproofed, damage to the top of the pool shell bond beam can occur with freezing temperatures.
