Can you use only one of the pumps at one time or do you have to use both of them always?

You can use one at a time :) I find that easier because my boobs are so huge!

Yes, you can do one side without the suction being effected. The tubing is separate for each side.

When you press the power button, both pumps would start already. I've tried using one pump only but the other one would still go on and continue to pump.

My wife always use both of them at the same to save time. That is why we bought double pump.

The pump always operates both, however you don't have to use both. My wife will often nurse one and then later pump the other, only attaching one bottle. So you can use it as a single or double pump.

It says you can use one side at a time, I almost always use both. I have used just one with the other attached and the lid on it, though, which seems to work well. I tried it once with just having the other side not attached, but it was much louder that way- even though that seemed to work too... I hope this helps. :)

You can use them one at a time but pumping one breast usually stimulates milk let down on the other breat so pumping both at once is best.

Yes. I have both shower heads every time I shower. You have the option to use one at a time.

It really depends how often you use it. I bought two extra sets so I could have three sets and wouldnt have to wash it after each use. This way I had three clean sets ready to go and just had to wash them all together three pumps later. I've never had to replace the original one yet.

You are able to pump both breasts at the same time with this system. You can control the speed and strength of the suction. It does come with three different flanges. I would recommend buying more bottles as they are great for storage after.

yes u can when the pump starts sucking air it will shut itself off...clogging hardly ever happens either....its a good pump so far for me

If I understand your question correctly, you're asking if you can use one check valve for both the sump pump and the battery backup, the answer is yes, as long as the two line tie into one line, but the system won't work as efficiently, you loose pressure from either pump, I had the same configuration and added a check valve for each system and the pumps work much more effectively and less noise from the systems.

Yes, you can. The flow is split between the two spouts so the flow is weaker, but you can use both.

You can disconnect the one tube so you can pump only one if you want (although I've found a manual pump is a lot easier to use while nursing at the same time!)

That I don't know. I've only owned the one fountain. I have had for over 10 years and replaced the pump only once.

It depends on where you have the check valve installed. If you have it inline after both pumps meet, then no you don't. If your check valve is attached to the main pump, then yes you would need another check valve.

It is possible to get them to work at the same time but only by very careful adjustment with the selection valve, the water flow from each will be low. I don't think it was designed to work that way.

There is another opening to connect the second tube, directly below. It has a plastic cover on it- to use it as a double, take off that plastic and hook in your second tube. To go back to single pump, cover the second opening again with the plastic cover you removed.

The best luck using this was utilizing two separate pumps! One for the air stone and the other for the bubbler

It not made to do this. Now after saying that, I have used two of them in dual assembly to purify water in my Motor home. You probably want to use it only with the hand pump as designed.

Yes it should not problem, basically you plug in your other pumps and as long as they can handle being cycled on and off you should be fine! I have had mine for over a year now with no problems.

Its called presta valves, you can either get a pump that can do both presta valves and the normal valves or just get some adapters for your valves to go from presta to the normal ones. They are not hard to find I bought mine at walmart. They just screw over the presta valves.

You can use two buckets at a time however you would need to run the additional two air hoses into the buckets in use by drilling an additional hole for the air line in the top of two buckets or connect the two air lines not in use to the air lines in use by a "t" fitting. The 4 air outlets on the air pump are always on. They cannot be shut off individually.
