Valve Section
Replacement,
Valterra/Magic

Note that this section is intended for repair of
an existing split type 'slicer' valve. In this example, I'm using a
Valterra center section to replace a freeze damaged Magic Valve of the
same type. No preferences to either brand, as they're both good
valves. The Valterra is what I had available at the time for a
replacement.

In this image, you can see in the
highlighted area that this particular valve has split in the handle section,
causing quite a serious spa leak when the pump is turned on. |
| This replacement is documented
rather quickly, with few pictures, but it's really nothing more than common
sense. That is, 4 bolts hold the valve together. Inside there are
two gaskets that, after a number of years, usually begin to leak. Adding
bad water quality to the mix does accelerate the rate of
deterioration. |

 |
| First thing to do is remove
the four through bolts that are holding the assembly together. In this
case, I was also able to remove half of the assembly from the spa so I could
work on it separately. |
| Thanks to some perfectly sized
gaskets from Onyx Water Products, I set this thing up so that the gasket seats
around the protruding ring edge from the flange. |
|
|
. |
 |
Using Permatex Number 2 sealant, I
apply a light coating on the flange. |
| Then position the
gasket. |
|
|
 |
 |
The new valve comes assembled as a
3 piece assembly, so what I've done is remove the bolts and separate the new
internal valve and gaskets from the new flanges. |
| Then, I do the same
application of Permatex on the mounted flange, along with a
gasket. |
|
|
|
|
Then I reassemble all the
components, and install the new bolts that were removed from the new
valve. All that's
left now is to refill the spa, and check for leaks.
