Each Wright water storage tank is manufactured to last providing you with the longest possible life when installed properly and when well maintained. The instructions that follow are guidelines to help protect your water storage tank. Please perform maintenance checks as recommended in the following.
Most of the inspections can be performed by the owner.
The following steps should be taken before your delivery:
A. Prepare a level pad for the tank. Our truck is equipped with a crane and can set the tank on your specific location as long as there is an accessible road.
B. The tank should be placed on a gravel base, a service we also provide.
C. Fill the ring with pea gravel.
The tank installation should be in conformity with Wright Tank (Manufacturer) specifications. Contact Wright Tank for any other questions about installation. (661) 948-1616
DISINFECTING YOUR TANK
For more information on disinfecting your water tank the link below shows California department of health instructions.
Any vegetation and soil which can trap moisture between concrete and steel, should be cleared as soon as possible from the base of the tank. Tree limbs and shrubs can cause scratches in the coating which could cause coating failure sooner than expected, so all brush should be cut back.
The area should also be inspected for acts of vandalism by trespassers. Unauthorized access to the tanks will be a possible liability for the owner of the tank and is a possible threat to the water system security and the tank. All manholes and man ways should be checked to ensure security.
The tanks foundation should be checked on a regular basis for deterioration which can cause major problems. Careful observation of the foundation is key to the inspection.
The presence of the following factors can be cause for immediate repairs: abnormal growth of vegetation, settlement, cracking, gravel spillage, signs of leaking, or exposed reinforced steel. Some foundation repairs may require the use of a contractor whereas other repairs may be done by those with less skills.
A. Concrete Ring Wall and Slab Foundation
1.Examine foundation annually for any fractures that may have developed. Fractures may cause eccentric loading of water and could cause structural damage.
2. Make Check of the base of tank to ensure:
a) That there is no space between the tank bottom and the foundation due to settlement of the foundation.
b) That anchor bolts (if in use) are tightened appropriately
B. Foundations on Gravel
Inspection of the foundation and the tank site should be followed by an examination of the water tank itself. Look for signs of leaking and corrosion, check connections and screens.
A leak may not be visible to the naked eye and can be detected by the presence of rust spots, saturated soil, mineral streaks and coating bubbles. If a leak is found contact the local dealer, or the tank manufacturer. Taking photos of the area that is leaking can be helpful in assessing the situation.
Check the conditions of overflow discharge screening and vent screening. Search for signs of debris, holes or gaps. Vent screenings also can be found on the tank roof. If the person inspecting the tank is trained to access heights and is equipped with the proper safety gear, the vent screen may be monitored. Any inspection of the welded tank roof should be handled with great care and caution.
NOTE:ENTERING THE WATER TANK SHOULD BE DONE BY A PROPERLY TRAINED AND EQUIPPED PERSON. EXTREME CAUTION NEED BE USED WHEN ENTERING TANK FROM ROOF MANWAY. WRIGHT TANK RECOMMENDS USING A GROUND LEVEL SHELL MANWAY TO ACCESS THE WATER TANK. IF THERE IS NO SIDE-SHELL MANWAY THEN CONTACT WRIGHT TANK FOR RECCOMENDATIONS OR ACCESS INSTRUCTIONS. (661) 948-1616
(Worker training is available to personnel through many sources including the Occupational Safety and Health Administration at www.osha.gov)
- Inspect the tank visually through the roof man way annually. If the tank has signs of rust, coating degradation or mineral buildup drain tank and check for leakage.
- Before draining the tank contact tank manufacturer for coating touch up instructions. Most repairs can be performed by untrained personnel.
- Carefully remove the side-shell man way (if applicable) to protect the neoprene rubber gasket.
- Use a soft bristle broom to remove any sediments that may have built up at the bottom of the tank. Rinse the tank with clean water and flush tank out if possible.
- Inspect submerged surfaces visually, including the deck and support structure for any signs of corrosion or damage to coating. Use battery powered lighting for inspection. DO NOT USE TOOLS OR LIGHTS POWERED BY ELECTRICITY INSIDE OF THE TANK.
- Check the paint coating for any sign of wear.
- If painting is required then talk to Wright Tank (661) 948-1616 for painting instructions.
- Check each interior accessories for wear or damage and repair if needed.
- If repairs have been made to the inside of the tank, be sure that all materials, equipment and tools has been cleared of the tank before replacing the man-way cover and putting the tank back into operation.
- Disinfecting the water tank may be needed before filling the tank with water. Contact Wright Tank for instructions on disinfecting of the tank.
Service of Accessories
Clear screen of any and all debris that may collect on or in the top of it. Check for deterioration and replace when needed. In colder climates check for icing of screen and snow blockage.
Nozzles and Connecting Pipes
Look for distortions in the tank wall connecting to the pipe. Distortion can be caused by a difference in the settlement of the tank and the pipe, resetting the pipe supports may be required.
Liquid Level Indicator
Check each of the following annually:
OEM Level Indicators
Follow instructions of manufacturer for the maintenance and inspection of the level indicator.
Valves, Sample Boxes, Sight Glass, Pressure Gage, Etc.
Inspect each annually for smooth operation and clean and repair as needed.
Outside Ladder, Cage, and Perimeter Handrails
Inspect annually tightening the bolts when needed.
An inspection of the tank should be done annually to insure the performance of the tank and evaluate problems and damages that may have occurred. The inspection should look for any signs of rust, leakage, coating damage,equipment functionality, and any and all other items that are directly influenced by the performance of the water tank. All repairs should be made as soon as the problem is identified.
Level controls, overflow, and venting systems should be checked on a monthly basis to make sure the tank does not get plugged or equipment stops operating.
FAILURE TO INSPECT AND/OR MAINTAIN THE WATER STORAGE TANK IN CONFORMITY WITH THE MANUFACTURER’S INSTRUCTIONS MAY RESULT IN VOIDANCE OF WRIGHT TANK’S GUARENTEE.
