Water pump with gauge

It’s easy to water pump with an air pump!
Just disconnect the hose from the hand pump. Fill the cylinder with water, enter into the cylinder, take the hose that had to the hand pump and suck to a descent vacuum (3- 4 zips), disconnect the hose from the cylinder. Every 5 minutes you have to connect and zip out water to hold a decent vacuum under entire session.
write down a measurement scale with a marker on your cylinder for better control. And before you start this technique you transfer your air pumping session to this.. but with water in the cylinder using your mouth to suck vacuum instead using the hand pump.
So lets say for an example that you pump 4 times to reach 4 Hg. That’s how many zips you will do with your mouth. Make shore that you stay just under your BPEL in the tube. And that’s why you must write down a measurement scale on your tube. For better control and progress.

This is how I do it! Easy and I get no negative side effect from it.

Take it easy if you’re new to this pumping technique.

The brake bleeder pump comes with the water trap

Great. I didn’t see the size mentioned of the water trap on amazon.co.uk. Is the size big enough for a cylinder? I imagine the water trap just as something wrapped between the cylinder and the pump?

The water trap is connected with an extra hose that is provided. If dry pumping the extra hose and trap is unnecessary and can remain in the box. The trap is isolated between two hoses (not directly attached to the pump).

I May be making it more complicated that it is. Really very simple. It basically is just a guaged pump that comes with a trap designed to catch brake fluid. Or in our case water. And thus you can pump dry or wet.

So you need that, a cylinder from leluv and the fitting sold at leluv. Pretty cheap

Male to Male Quick-Release Fitting Vacuum Pump Cylinders Single or 2-P

Cylinder there too pretty cheap.

Great this makes perfect sense. I completely misunderstood the concept of a water trap :) Thank you and for the links above. I ordered the three items you mentioned and my pump already arrived, now waiting for leluv :)

I just got the orders and I made the pump. Does anyone have any tips on how to use it? I am having a lot of problem water pumping. I tried to fill the cylinder with water (which was very annoying as it’s hard to put water in it). Then I tried to pump but the water already went into the pump right from the get go (some remained in the water trap but the water was just a lot that went in there). So I really need some practical advice on how to water pump!

Thanks!

I can’t help you with the mechanics of it i just provided the info from the other thread. Info came from memento.

Maybe search water pumping I remember there being a great thread on it.

There is already pressure test video for waterpumps pressure

Hold on, I’m really confused here.

Why do you need a water trap with the brake bleeder pump? It makes no sense to me.

Fill the cylinder with water, pump a few times, fill cylinder to top, stick your dick in, pump to vacuum desired. Am I missing something, because it works like a charm for me. I don’t have a water trap and don’t understand why you would need one.

The main problem I’m having is that the water gets into the pump. If you hold the cylinder upside down to put your penis in, the water flows to the pump and the pump gets water in it.

Mine pumps the water no issue, builds vacuum. Yours won’t build vacuum if water gets in it?

It pumps it vacuum actually, but still the water first went in the pump already and hence the pump is all wet inside. This is not good for the pump. I was lucky that the pump still works after my failed attempt I think.

Ah I see now. If it is not an electric pump, water really shouldn’t hurt it except for maybe rust depending on the pump metal type and water quality. If you want to be careful with your purchase though, I completely understand. I figure I’ll get a few years out of mine pumping water, and for 40 bucks, I think it is worth the less hassle.

I’m assuming there are o-rings inside, I’ll probably put some silicone lube through there every once in a while to relube the o-rings and keep them from dry rotting.
