The BEAVER Tap Wrench  

A new tool specifically designed and developed for 
 Plumbing Compression Tap Connectors

 

I think it would be a very reasonable statement  that Bath and Basin Tap connections can be one of the most awkward jobs that a plumber is regularly called on to do.

They are especially difficult because of their position.  They could have been there for decades. They are often stuck fast with accumulated corrosion where water has run down the threads.

Tap Connector Tools.

             

All the above have their limitations.  Because the nuts vary so much in dimension,
the tools with a fixed jaw are virtually useless most of the time.

                          poor fit of existing tools

Of the two, the spring loaded tap wrench, whilst superior to the other, is still 
awkward to get into position, has a tendency for the head to swivel and offers limited leverage.  (You can probably see that the handle is already bent!)

 The "beaver" 15mm and 22 mm wrenches have received excellent feedback from users with some stating they would be lost without them. Rather than repeat how they work you can read it in detail on the relevant pages - beaver 15 or beaver22

Put simply, they accommodate the various nut sizes by driving on the flats of the nut.

We have now applied this principle to a Tap Wrench.
                      

There are differences with the normal wrench shape as the nuts holding the tap connector are generally smaller than the normal compression fitting. Especially for 22 mm pipe the nuts vary from approx. 28.3mm to 30mm across the flats.

Does it Work?

Each wrench has a square hole situated behind the head. 
This is to accept a socket extension, (or socket wrench if you have the room.)
The hole is 1/4 inch for the 15mm and 3/8th inch for the 22.

Therefore you can use whatever combination of !/4  / 3/8th / adaptors / extensions is best suitable for the job involved.  Or, indeed, with a suitable adaptor, a 1/2  extension and wrench. 

Testing, Testing

To simulate the thread being tight, or stuck with corrosion, the first trial had the nut fixed with Loctite and allowed to harden.  
The 1/4 inch extension and racket dealt with this fairly easily.

For the next trial we used bearing fixer. This is similar to Loctite but much stronger as it is not meant to be undone. It is to fix loose bearings in place permanently.

This proved beyond the leverage of the 1/4 ratchet!  However switching to a 3/8, with adaptor soon had the joint  loosening.

The point is that the wrench head worked without slipping or being deformed.

It gripped the nut flats so securely that, under the  extreme  test of the "bearing lock" test, it marked the flats. 
               

Another advantage of the socket drive is that the heads can be used as a simple additional wrench.

              

 With the handle at any angle is best!

Advantages over Standard Spring Loaded Wrench

No moving parts to wear or fail.

Will not slip under pressure. (Nut stuck with corrosion etc.)

Can be operated single handed.

Easily extendable to suit the job.

Benefits

Will not need replacement!

No more banging your hand on bath or wall when the sprung tool slips!

No more trying to open the jaws with one hand whilst guiding the tool
into position with the other. (WIth water running down your arm!)

Use whatever combination of extensions give best access.
