How to replace a blocked
bottle trap |
| |
| Women with long hair cause a major problem when
it comes to plumbing, but who ever invented the 'U' bend or
bottle trap must have been a man!
When Dyson first started to look at the design of vacuum
cleaners he immediately saw the potential for a complete re-design.
In effect that is exactly what the design team of Hepworth
Plumbing have done with the new Hep vO valve. The self sealing
valve opens under the water pressure of an appliance emptying,
and closes to form a tight seal after the appliance has discharged.
When a bottle trap becomes blocked it is often easier due
to the low cost of the product to simply replace it. The Hep
vO valve is slightly more expensive than the traditional bottle
trap but it is well worth the investment as it is less likely
to block or need replacing in the future, the following case
study is a step by step guide for the replacement of a traditional
bottle trap using a hep vo valve. |

The first task is to remove the bath panel, in
some instances the whole panel is removed whilst in others only
an access panel is made available toward the front end of the
bath, either way the panel should be removable for maintenance
purposes. Changing a bottle trap is relatively straightforward
job, however, the job is often complicated by the limited space
that is available.

The next step is to remove the bottle trap. Before
you disconnect the bottle trap make sure that the bath is empty
and insert the plug as a safety measure, carefully unscrew the
top connection of the bottle trap taking care not to disturb
the plug fitting and overflow. |
| |
| |
 |
|
In this example the join at the other end of the
pipe is a simple a push-fit connection which can easily be pulled
out, it was easier to remove the bottle trap and short piece
of pipe rather than just the bottle trap on its own. |

| |
 |
|
As can be seen bottle trap's are prone to blockages
by an accumulation of hair, soap and grease, hair can also cause
continual siphonage which in extreme cases can cause the loss
of an effective seal and foul smells to enter the room. |
| |
| |
 |
|
The Hep vOvalve eliminates this problem by allowing
waste water to flow straight through the valve without passing
any bends or restrictions as can be seen the threaded connection
can be made vertically or at right angles and they are available
in 40mm for the bath and 32mm for a sink, the opposite end is
a push-fit fitting. |
| |
| |
 |
|
Fix the Hep vO valve to the waste outlet then
carefully measure the pipe, allowing for the full compression
socket depth, to fully penetrate into both fittings. |
| |
| |
 |
|
Cut the pipe to length, then carefully remove
any burrs or sharp edges from the end of the plastic pipe. Bevel
the ends of the pipe and if necessary remove any external sharp
edges. If you are re-using the existing pipe, thoroughly clean
the pipe with an abrasive scouring cloth, and check that the
pipe section to be jointed is free of any surface damage which
may affect the joint seal. |
| |
| |
 |
|
Disconnect the Hep vO valve. The Hep vO push-fit
fitting is of the compression type and it is often easier to
slide the seals over the pipe rather than trying to push the
pipe into the joint, which may cause damage to the seal. Unscrew
the cap from the Hep vOoutlet. Insert the pipe fully into the
socket. Slide the rubber seal, nylon washer and screwed cap
up against the face of the socket, and tighten the cap by hand,
(check that the cap is square to the body and does not 'cross
thread') hand tight should be adequate to form a seal. |

|
When fixing horizontally to an appliance outlet
or sloping pipe, in order to prevent standing water and to provide
a continuous fall, the Hep vO valve must be fitted with the
ribs underneath. The remaining joint in this example is a simple
push-fit connection, you may find a small amount of washing
up liquid will help to lubricate the seal, offer the assembled
Hep vO valve and insert the pipe, push to make the connection. |
|
 |
| |
| |
 |
|
Finally, screw the Hep vO valve to the plughole
waste to make the final connection and seal. Run the water
to test for leaks, if this proves OK, fill the bath then test
again. Once you are completely satisfied replace the bath
panel.
