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.

When i put my hose in to vaccum i lose suction but with out hose it will **** your hand down the pump is workin great


Are you filling the hose with water before you put your hose into the skimmer? Put your vacuum in the pool - put the other end of the hose over a discharge ... when the air bubbles stop coming from the bottom ... , put your hand over the end of the hose and then stick the hose into the skimmer suction.

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.

Why is my filter system losing prime?


It could be one of these issues with your pool filter. Try these solutions. If none of them work, let me know and I will do some more research.

1. D.E. coated with normal accumulation of pool dirt, algae, etc.
Solution: Bump your filter.

2. Pump strainer basket or skimmer basket is clogged.
Solution: Clean

3. Pump impeller vanes clogged.
Solution: Cleaning with a stiff wire brush through the pump strainer opening will usually work. Alternate method would be to disassemble and clean.

4. Air Leak on suction side of pump.
Soultion: Check cover gasket, hand knobs, hose, clamps, etc. Replace or tighten as necessary.

1/2hp Hayward Pump for existing inground pool


you will be fine with the 1/2hp. The Hayward will move quite a bit of water as well. It may not move as much water as the 3/4hp but it's very close and the 1/2hp will cost a little less to operate so if anything, you may just have to run it for one additional hour per day to compensate. You will be surprised how much water a 1/2hp will move. The only issue with smaller pumps is if you have pop-up cleaner heads or a suction driven automatic cleaner such as a kreepy krauly, however, if a 3/4hp will run it, a 1/2hp will run it as well. You can install a larger motor on the super pump but it will not move more water unless you upgrade the impeller as well. Just make sure you don't use a bigger impeller than what the motor is rated for because it will strain the motor and cause it to overheat. Hope this helps.

My pool pump is 2 months old. It is a Hayward 1hp


The capacitor is probably bad. It's under the cover on the side of the motor, Take a look and smell it. A motor shop has them, or Grainger

My hayward de filter will not filter over 1 hour


How much DE are you putting in it??? If it is a EC40 then no more than 4 small coffee cans of DE.
If it is an EC65, then no more than 6 - small coffee cans of DE. ( you can even shy back by a 1/2 of can of DE, without any problems.
Is the pool green??? If so, the filter will continue to plug up until clean.
Keep your Chlorine abit on the high side...DE filters run best with a chl reading of 3.0

NOT FILTERING, NO SUCTION, CHANGE SAND,,,SINCE DAY ONE..WRONG HP?


You are correct. Your lines are extremely small for this system and the pump is to small for this system. You are going to have to do a total upgrade. from the pump to all the lines. I know this is bad news, but it is a common problem for system that where put in more then 10 years ago
