    Can you give me more of an idea of your setup? I need to know where is the pump located relative to the base of the pool? What size pump are you using (pump head pressure/ horsepower) That information should be on the name plate of the pump. What size hoses do you have and how long are the hoses?

    Also, I assume you are trying to fill pool? Correct?

    Forgive me for asking so many questions, but I hate to steer people in the wrong direction.

I have a model 109163. I'm trying to pump water from a creek. The suction hose is about 6 ft below the pump and 12ft long. The output hose is running about 300 ft at a gradual incline to about 10 ft. My...


In order for the pump to **** up water, it must discharge air. Try this. Install a hose bibb (faucet) in the discharge line over top of the pump. Fill the pump housing with water, turn on the pump and open the hose bibb/faucet until full water flow is established. Almost all air should be out of the pump and suction line at this time. Now when you close the hose bibb/faucet, the pump will have plenty of pressure to fill the long discharge line.
Suction line should be 2-1/2 inch if that is the pump suction size.
What size is your discharge line?
There should be a check valve/foot valve on the end of the line in the creek to keep water in the pump once it is primed.

No suction for pool vac


If you are not getting any suction to the vacuum, but the pump is working fine the rest of the time, start by checking all of your connections that conncets the cleaner to the filter and pump. Make sure there are no cracks, lose hoses, etc. Then, check for the following common problems with your pump that might cause low pressure in pool pumps:

1) Pump not primed

2) Leakage of air into suction system

3) Impeller clogged

4) Valve in suction or discharge line partly closed; Suction or discharge

line partly plugged or too small.

5) Plugged basket in skimmer or hair in lint strainer

6) Dirty filter.

If you are seeing air bubbles in the leaf pot on the pump, you have an air leak on the suction side somewhere between the pump and the pool. Check the pump lid o-ring for any dirt, leaves, etc. Make sure the O-ring on the lid is not cracked, dry (lubrication like Aladdin's Magic Lube) or compressed or flattened. Also check your union or threaded connections to the pump suction (end) to insure they are tight and sealed. If this is an in-ground pool, and equipped with valves to control skimmers and bottom suction, close each valve separately to see if the air bubbles diminish. If the bubbles diminish when the valve is closed, then the air leak is in the closed section from that valve back to the pump. If the air leak increases, the air leak is in the still open line. Since the Kreepy crawly works on suction and increases the vacuum, the air leak will become more apparent, resulting in a loss of pump efficiency and flow, resulting in lost performance on the cleaner. If so equipped, close off the bottom drain valve and increase the suction on the vac line. I can provide further details as needed, but will need more information from you regarding actual equipment layout.

If you have a pressure gage it would help .. if the pressure is high then there is probably an obstruction in the return pipe to the pool .. if the pressure is low then there is most likely a restriction in the supply or suction side of the pump .. this would seem more likely to me from your description, there may be something obstructing the flow into the pump, a clog, a collapse hose from the suction, some flap of pool liner .. something like that ..

Pump won't **** when attach the hose


Its very possible that it is not a problem with the pool pump, but a problem with the conncetion to the vacuum hose. If you are losing pressure only when you vacuum, make sure that your connection is secure and you have no holes, cracks, etc. in your line. If you think that there are definate pool pump problems, check for the following problems.

1) Clogged or restricted strainer or suction line

2) Plugged or restricted discharge line of filter (high

discharge gauge reading).

3) Air leak in suction (bubbles issuing from return fittings).

4) Pump operating underspeed (low voltage).

5) Plugged or restricted impeller.

Hi my name is Juan and I was a pool tech in california now located in georgia and let me try solve this if your filter is dirty it created a high pressure in your filter gauge with poor suction to check this bypass the filter and see if suction increase sometimes your gauge is bad and is not showing the true reading but if is good and pressure is to low then is so clear you have a suction leak try to replace the pump lid O ring and if you have spa check the intake valve where you select pool or spa if you don't have spa then the air leak is in the pipe connected to the pump suction side believe me this is a common problem
