The pool system pressure gauge, located between the pressure pump and the filter, can be very useful in many ways and ward off certain swimming pool problems. The main purpose of this gauge is to monitor the water pressure of the system, which is needed to maintain water circulation . Knowing the variationsof this gauge on a periodic time table is a basic and and all important part of maintaining your swimming pool.Life is too hectic for unnecessary swimming pool problems in this busy world.
Water Pressure is Higher Than Normal
Water Pressure is Higher Than Normal
If the pressure gauge is registering a reading higher than normal, the problem is most likely one or more of three possibilities.
1. The filter is dirty and either needs replaced or back flushed, depending on your type of filter . Refer to your manufacturers recommendations in your owners manual for complete instructions .
2. There could be an obstruction in the line after the water leaves the filter.The directional hydrostream eye could be shut, where the water enters the pool. Some people like to play with these, not knowing what their intended purpose is.
3. Or the diverter valve is not positioned correctly.This could truly cause swimming pool problems, perhaps cracking the diverter valve body.
Water Pressure is less Than Normal
If the pressure gauge is registering a lower than normal reading, there is an obstruction in the line to the pump. If the pump cannot get enough water then it cannot build, and keep pressure in the system and the water will not circulate correctly in the pool. This in turn can create many more swimming pool problems:
There are a couple of possible causes for this:
1. The skimmer and or pump basket is full of leaves or debris and needs emptied; not allowing enough water into the supply line to the pump.
2. The water level in the pool is low and thus cannot flow into the skimmer as required. In which case water needs to be added to the pool. This is an easy fix to the problem.
Fluctuating Water Pressure
If the pressure gauge is fluctuating, there is an obstruction at the skimmer weir or the pool water level is low. Anything that does not allow enough water to enter the skimmer will cause a fluctuation in water pressure. If the pump maintains it; prime it will build pressure once the skimmer fills up with water, but then the pressure will drop once again when the skimmer runs dry, because there is not enough water being supplied to the pump. When the pump is not supplied enough water it will cavitate and cause fluctuations in water pressure. This vicious cycle continues until it is corrected. Eventually the pump will have no water to draw in and the pump will run dry, possibly over heating the pump, rendering it useless…more swimming pool problems.
Therefore it is necessary to keep the correct amount of water in the pool at all times. There is commonly a hash mark by the skimmer inlet, this is the correct water level. Keeping the water level within this range should allow the pump to operate correctly and skim leaves and other debris from the pool surface; eliminating these swimming pool problems.
Monitor The Water Pressure
Check the pressure gauge periodically while the pump is running for the pressure of the system every week is normally a good schedule to be on. It is a good practice to keep a written record of the water pressure, or at least mark the top of the gauge with a marking,to be able to compare the pressure readings.
Every time the filter is changed or cleaned the pressure should be recorded. The filter should be cleaned, replaced, or back flushed when there is a gain of 10 psi or more on the gauge. Be sure to check your filter’s owner manual for the manufactures recommendations. It is important to maintain water pressure in the system to circulate the water in the pool to filter the water and keep it clean to help eliminate swimming pool problems.
