Utilitech LPT-52 52 Gallons Vertical Well Pressure Tank

IMPORTANT INSTRUCTIONS BEFORE INSTALLATION

1. All piping and electrical wiring must adhere to state and local codes. If there are no state or local electrical codes, the electrical wiring must follow the National Electrical Code, NFPA 70. Check with appropriate community agencies or contact your local electrical and pump professionals.
2. Install the tank as close as possible to the pump pressure switch to reduce friction loss and the elevation difference between the tank, water supply main, and switch.
3. After installation, be sure the pressure switch is set low enough to shut the pump off. If all valves are closed and the pressure switch setting is too high, the pump will run continuously without water flow, causing overheating and damage to the pump.
4. A pressure relief valve must be installed in the piping adjacent to the pump tank.
5. The following may cause severe damage to the tank and/or piping and will void the warranty:
6. Failure to protect the tank against below-freezing temperatures.
7. Pumping chemicals or corrosive liquids.
8. Pumping gasoline or other flammable liquids.
9. Operation at pressures greater than 100 PSI with no relief valve.
10. Pumping liquids hotter than 120°F.

This pump tank is designed and intended for cold (ambient temperature) water storage at a maximum pressure of 100 PSIG. Any use other than with cold water, or at a sustained or instantaneous pressure in excess of 100 PSIG, is UNSAFE. A pressure relief valve of adequate size must be incorporated into the system. The relief valve must be selected to pass the full capacity of the pump when the pressure in this tank is 100 PSIG or more.

Consult the pump manufacturer for the pump capacity at relief pressure. The manufacturer of this tank does not accept any liability or other responsibility for personal injury or property damage resulting from improper use, installation, or operation of this tank, or of the system of which it is a part.

Install a 100 P.S.I. or less pressure relief valve directly into a fitting of the plumbing. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below, the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances.

Excessive length (over 15 feet) or the use of more than two elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to the discharge drain unless a 6 in. air gap is provided.

To prevent bodily injury or hazard to life, the valve must be able to discharge large quantities of water should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.

The Discharge Pipe:

• Must not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
• Must not be plugged or blocked.
• Must be installed to allow complete drainage of both the pressure relief valve and the discharge pipe.
• Must not have any valve between the relief valve and the tank.

IMPORTANT

It will be necessary to expel all air from piping after new installations, repriming, and after pumps have been disassembled for repair. To purge the air, first open a faucet the greatest distance from the pump. With the pump allowed to run, wait until a steady stream of water is coming from the faucet. At this time, close the faucet for several short intervals. If, after this, air is still in the lines, check on the suction side of the pump for piping leaks. When standard-type tanks are replaced with this tank, all air charging devices, bleeder orifices, and air volume controls must be removed.

The pump tank has been shipped with a factory precharge as indicated on the tank label. If your pump start-up pressure is different from the factory precharge, adjust the tank pressure to your pump start-up pressure with the empty tank. This can be accomplished by simply bleeding air from the valve at the top of the tank with an accurate pressure gauge. Using the same standard air charging valve at the top of the tank, a tire pump can be used to raise the tank pressure. Raise the pressure slowly, checking it periodically with an accurate tire pressure gauge until the desired pressure is reached.

TANK SPECIFICATIONS

PIPING

PVC pipe is shown in the illustrations, but copper or galvanized steel pipe may be used if desired. All piping must be clean and free of all foreign matter. ALL JOINTS AND CONNECTIONS IN THE SYSTEM MUST BE AIRTIGHT. A pinhole leak will prevent proper operation of the system (this is the most common problem). Use thread compound on all threads unless specified otherwise.

DRAINING FOR SERVICING OR FOR WINTER

The system should be drained before it is disconnected for servicing, or if it is inoperative for an extended period of time, or if it is in danger of freezing. To Drain:

• Follow the instructions in your pump installation manual to drain the pump.
• Open the tank drain cock to drain the tank.
• Drain all piping to a point 3 feet below ground level.

DIAPHRAGM TANK INSTALLATION

Diaphragm tanks are recommended for clear water applications. Vertical tanks are the most commonly used tanks. However, horizontal tanks and in-line tanks may be used where space is more critical. See Tank Specifications for tank capacity.

General Materials

• One can use PVC cement (read instructions carefully)
• One can thread compound (read instructions carefully)
• One 1 in. gate valve
• One 1/2 in. relief valve
• Enough rigid 1 in. PVC pipe and couplings to reach from the pump to the pressure tank to the service line
• One male 1 in. PVC adapter
• One 1 in. x 11 in. tank cross or 1 1/4 in. x 13 in. depending on acceptance fitting, see Chart 1
• Two 3/8 in. plugs
• One 1/2 in. boiler drain
• One 1/2 in. street tee

REMINDER: All joints and connections must be airtight. A single pinhole leak will prevent the proper operation of the system. Use thread compound on all threaded connections unless specified otherwise.

TYPICAL SUBMERSIBLE PUMP INSTALLATION

STEP 1

Complete pump assembly and electrical connections as specified in the pump installation manual. Place the tank in the desired location and level it.

STEP 2

Thread the tank tee into the pressure tank so that the two 3/8 in. holes in the tee face upward. Thread the street tee into the front of the tank tee. See Figure 1.

STEP 3

Thread a 3/4 in. male PVC adapter into the inlet side of the tank tee. See Figure 2.

STEP 4

Thread the pressure relief valve into the top of the street tee. Thread the 1/2 in. boiler drain into the front of the street tee. Cut and cement as many sections and couplings of PVC pipe as needed to connect the 3/4 in. male PVC adapter to the pump discharge. See Figure 3.

TYPICAL JET PUMP INSTALLATION

STEP 1

Thread 10 in. x 1 in. nipple into the pressure tank. Thread the tank cross into the nipple so that the two 1/4 in. holes in the tank cross face upward. Thread the street tee into the front of the tank cross. Thread the pressure relief valve into the top of the street tee and thread the 3/4 in. boiler drain into the front of the street tee.

STEP 2

Thread 1 1-in male PVC adapter into the inlet side of the tank cross.

STEP 3

Thread one end of a 1/4 in. x 3 in. brass nipple into the bottom of the pressure switch. Thread the other end into the left 1/4 in. hole of the tank cross. Thread the pressure gauge into the right 1/4 in. hole of the tank cross. Cut and cement as many sections and couplings of PVC pipe as needed to connect the 1 in. male PVC adapter to the pump discharge.

The complete installation should look like the drawing shown below. See Figure 8.

Setting the Tank Pressure

The tank pressure must be set 2 PSI lower than the pump cut-on pressure. Check tank pressure with a standard air gauge valve at the top of the tank as needed.

Other Tank Installations

Where space is a critical factor, the in-line tank may be used, or the pump may be mounted on either the horizontal or vertical tanks. Various installations are shown below. Also, to increase tank capacity up to even industrial levels, multiple tanks may be installed on the same line, as shown to the right. Consult your local pump professional for your particular installation.
