Newport Brass Faucets
Roman Tub
The term “Roman Tub
Faucet” refers to a faucet mounted on the rim of a tub or the deck
behind the tub. It is used to fill the tub with water. Another term
synonymous with roman tub faucet is “deck mount faucet”.
The standard drill
hole size for all of our roman tub sets is
1-1/4”. Roman tub sets do not come with hoses or a tee assembly; these
will be provided by the plumber since it depends on how the plumber is
going to rough in the valves either using a sweat connection (copper) or
an IPS connection (threaded). This allows the plumber to place the
handles wherever the customer wants, with the only exception is that the
hand shower does have to be located somewhere near the diverter as the
hose which is included is a 5 foot hose with another 2 foot
under-mounted hose.
As with shower valves,
there are two components that comprise a roman tub faucet:
Rough
– the rough is the valve under the deck of the tub and is not seen. It
is the working mechanism and controls the flow of water along with the
quick connect to attach the spout to the deck. Approximate flow rate
for ¾” roman tub valves are as follows; 8-12gpm @ 45-60psi, these flow
rates are affected by the PSI rating (water pressure) and the design of
the spout. Roman tub faucets, like shower faucets, require you to give
the plumber the correct rough-in specifications. This is critical so
the trim will attach to the rough correctly; please refer to the stem
length handout.
Trim
– the trim is all of the finished pieces of the faucet and is what is
visible to the eye. It gives the customer the opportunity to select
what they personally like in terms of style and finish.
In some cases, the
rough and the trim are shipped and purchased separately or the rough and
trim will be packaged together depending on how the dealer orders it.
As with shower valves, most often the rough is shipped to the job site
before the trim. This is because the rough is one of the first items
that the plumber installs and is needed to pass the first inspection.
Most plumbers want the trim shipped at the end of the project so they
don’t have to worry about theft or damage, also if the trim is not in
stock, getting the valve ahead of time allows
most of the work in the bathroom to be completed and then just attach
the trim at the end when it arrives.
We offer two different
8” wide roman tub spouts (2-231 & 2-238) which do not have any specific
trim associated with them, it can be used with any roman tub trim with
or without a hand shower that is offered by Newport Brass. However you
do have to be careful when selecting the trim where as the handle and
escutcheon may have to be ordered separately depending on what series
that they are trying to have the handles match. Also with these roman
tub spouts there is no quick connect included, they attach with either
one or two ¾” IPS nipples threaded directly.
Common Issues and
Solutions
Quick connect
Quick
connect nipple
Most of the time when
the customer states that the nipple is missing from the quick connect it
is located inside the deck housing. When looking at the quick connect,
if the opening is 1” diameter hole than the nipple is missing, if the
opening is ¾” then the nipple is there and they just need to pull it out
of the deck housing.
Teflon tape
Always make sure that
they put Teflon tape on the nipple as instructed on the installation
instructions. If they do not then the spout will leak at the base, also
if they overload the Teflon tape then it has the ability to leak from
there as well, but that is typically not going to be the case.
Correct rough-in kit for trim
Always make sure that
you know exactly what trim is going to be used before installing the
rough in kit. If the customer or dealer is insisting on ordering the
rough in before knowing what trim is going to be used try to discourage
this as best as possible. If the dealer orders the wrong rough-in to
fit the trim or if the customer decides to change the trim at the last
second after the rough-in is installed then they have to choose trim
that uses that same rough-in kit. If they choose a trim that uses a
different rough-in the spout may not fit because of the spacer that is
used on certain sets and also the stem height will differ between series
for the handles.
Water Pressure
The max water pressure
for the roman tub valves is going to be 60psi, if the PSI is greater
than 60psi it will cause either the spout to leak when the hand shower
is on or the hand shower to leak when the spout is on. Water pressure
min/max is 45psi–60psi.
Water Hammer
A common complaint
that we receive from customers is that the valves are causing “water
hammer”. Basically “water hammer” is the loud banging noise
occasionally heard when a valve is quickly shut off. With non-ceramic
disc valves, this could be caused by a loose seat
washer, however Newport Brass only offers the ceramic disc type
of valve where this problem would no longer exist. “Water hammer” today
is often found to be caused by the pipes not being properly held place
or it is the sudden stop of the water from closing a ¼” turn cartridge
in a ¾” valve. The other possible cause for this is to make sure that
the piping underneath is strapped down securely, other than that they
would just need to turn the handle slowly when turning the water off.
Inlet/Outlet
If the dealer,
plumber, or end user calls and complains about the spout or hand shower
leaking or no water is coming out at all after the water pressure has
been verified and the diverter cartridge has been replaced, another
cause could be if they plumbed the inlet/outlets incorrectly. Please
see the diagram which shows the correct way to plumb the tub set and
make sure that it is installed accordingly.
