Question about Pentair IntelliFlo VS-3050 & VS+SVRS Variable Speed Pump -

General question, when the pump stops, there appears to be air leaking in around the cover seal. I can see air bubbles appearing at the rim. This is a new unit and I have greased the oring. Is this normal?

Usually if the o ring is leaking you might actually hear the air as it leaks into the pump. If that's not the case you could have some other suction leak in your piping. If you have valves on your suction lines perhaps to select skimmer or main drain, check them for leaks. If you have a chlorinateor, check the hoses and fittings and it's lid. Any air getting into the system can show up in the lid as the water in the filter tries to return, continuing the vacuum till pressures are equalized.

Either someone is letting the air out of your tire or it has a leak. Obviously the shops you have taken it to are incompetent if they can't find a leak. A good shop will submerge the tire and rim in a vat of water and look for air bubbles. If you have alloy rims, occasionally the rim may have "porosity" where the air bleeds out thru the center of the rim between the tire beads. A good rim shop will have sealant that is sprayed or brushed on the rim center to seal it.

Air in whisperflo window, bubbles from pool jets


This is a air leak on your suction side between the skimmer and the pump. You will not see water in the yard on the suction side usually, only the return. It is usually just the fittings around your pump or the seal around the pump lid, check those first and make sure you do not have a loose clamp or a damaged or dry seal. If that is not it then call in your local service guy to determine where the leak is. They will most likely pressurize your suction line to find the leak. Hope that helps.

Why does my rival seal a meal not seal?


The sealing mechanism is not working properly. Make sure there is no debris in the path of the seal wire - if so the area under that material will not be sealed and there will be leaks.

My sprayer is new, but does not keep the pressure, any idea's? It's a 2 gal, pump up type sprayer.


Check under the lid/cover for a rubber gasket. This may have gotten unseated when putting the sprayer top on. It must form a tight seal around the lip of the sprayer top in order to keep the pressure. Alternative: Put water in the sprayer leaving some air on top to build pressure. Put a few drops of dish soap inside and gently stir. Put the cover on, and tilt the sprayer to coat all areas at the top. Start pumping and see where the bubbles come out---there is your leak. If it is near where the sprayer hose enters, and it is a permanent mount, you may have a bad seal. If the sprayer hose unscrews, you may need a new rubber washer inside. If bubbles come out of the wand, or other plastic seams, you may have a crack in the plastic. Depending on the location, you could epoxy over the crack to seal it permanently. Good luck.

Sounds like you have a minor leak somewhere. most likely when the system is off the water is siphoning back into pool, and air is slowing seeping into system. Air can be getting in anywhere there is a joint, fitting, valve, seal, union, etc. Leaks can be broken down into two types: leaks on the suction side and leaks on the pressure side. Leaks on the pressure side are relatively easy to spot as you'll see water leaking while the system is running. Leaks on the suction side are harder to find as they **** in air which is obviously not easy to see or find. When the system is running look closely for leaks everywhere. If you find any fix them one at a time till the problem goes away. On the suction side, try wiggling and twisting things to see if you can find anything loose. Replace all union o-rings, the pump basket o-ring, leaf trap o-rings, etc., and see if problem goes away. If you have any 2 or 3-way jandy valves, try turning them while the system is running and see if any air gets in the system. If so you probably need to replace those o-rings as well. If you suspect air is leaking at a fitting somewhere, take some black electrical tape and wrap it tightly around the joint several times to fill the crack (this only works on suction side) this is a temporary repair, but works great to find and temporarily fix an air leak. I've seen people leave a repair like this for over a couple years and still work find, although I don't recommend it. If you find a leak at a pvc fitting, or a threded fitting that is not easy to fix, for example you may need to cut pipe and re-plumb several fittings and valves, there is another type of temporary repair that sometimes works very well. What you do is clean the area very well, take some RTV silicone sealant, and rub it as best you can around and into the leak, then turn on the pump for about 2-3 seconds (this sucks the glue into the crack) then rub more glue into the area as best you can. let this dry over night. If you still can't find the problem you most likely need to call a leak detection company, or get creative and start plugging and pressurizing things to find the problem.

probably a "O" ring as the seal
if the pump is doing what it is supposed to be doing and everything is normal. I would not stress about air under the cover as water contains air in suspension ( how fish get their oxygen to live) and from the turbulent action of the pump impeller , some of that air will be released and collected at the highest point of the flow line
