Hose + Shower + Floor 2 Cold - As Built 2

​

​

Hose bib, attached with trim screws. Located by drilling a 6” screw from inside. Used ¾” hole saw from outside, and inside to go through 2x blocking. PEX length was 3’, trimmed at end.

5” hole drilled on inside wall, blocking inserted to outside wall to screw bib into. Filled with insulation, and used interior block with suspension clamp.

Prepare double tee assembly for second floor. Drill 1-¼” hole to second floor. Measure at 74”.

Result of 74” of ¾” line, up to double tee and connection to water expansion. Note that in this build, we ran an expansion of cold water only, assuming another heater in the addition.

Shower Assembly is 2 drop ears + eccentric adapters put together in a vise. Faucet is attached, and that locates the Faucet Assembly exactly on a 2x4 block, 10” long. Then faucet is unscrewed. 1-¼” hole saw is used at 6” separation at 8” above tub rim. Drop ear ends exactly at back surface of tub. Front trim has escutcheon touching tub, and a thread or two exposed in front of escutcheon. Drop ears metal ends at edge of 2x4. Actual valve mount block height = .

Dropears accessible so that PEX can be attached and removed. Remember the PEX insert. Double tee mounted on another block about 5” above floor.

Finish running the ½” to shower, toilet, and bath sink 2. Note that bath sink 2 is a curve, not a fitting.

Run hot water line - about 10’4”. Bend with Pipe Bend Support. Cap is 4” in front of kitchen wall - 16”. 78” for the cold inlet. Note wide loop.

Hot water outlet - 21” long, sticks out 4” from kitchen wall surface, mounts 3” away from bathroom stud faces.

Hot Water Feed - Planning

​

1. Drill ¾” hole through ceiling, for ½” line to 2nd floor.
2. Measure and cut line to 2nd floor ending with a ½” tee
3. Measure and cut line - ending with ¾-¾-½ tee to first floor.
4. With a ¾” line, supply the kitchen sink and bidet via cross to reducer assembly (which continues to ½” shower)
1. Don’t supply the kitchen sink - until second wall is framed in.
5. Drill out mounting block for bidet and friction fit the line.
6. Supply the shower 1 - do trim later
7. With a ½” line, supply the bathroom 1 sink via a ½” tee
8. Supply washer
9. With ½” line, go to second floor -up to a tee.
10. Mark and cut a line for bath sink 2
11. Mark and cut a line for tub 2.
12. Tim out tub 1.
• Attach drop ears and adapters
• Attach faucet
• Attach to a 10” 2x4 with drop ear metal to edge of wood, locating drop ear spacing on the 2x4
• Take off faucet.
• Mark the 4-6-8 rule on tub
• Drill out tub with 1.25” hole saw, making sure that the hole separation matches the drop ear adapters
• Mount Faucet Preassembly on back of tub.
• Attach faucet to verify it fits and that the escutcheons go all the way to the tub surface.
• Attach water lines
• Do shower head mounting block on both tubs.

Run hose bib line.

1. Drill out 5” hole, save punchout to retrofit for PEX holder
2. Mount a hose bib mounting block on the exterior wall, so that hose bib can be attached firmly at 36” high
3. Cut line to length
4. Mount hose bib outside

36” high

Run ¾” cold line to second floor.

• On the second floor, build double tee assembly, attach ¾” to water expansion line, and attach expansion line with PEX mount clip. Measure length on 2nd floor
• Drill through floor inside the wall cavity on 2nd floor using a small hole saw for the ¾” PEX.
• Measure length of ¾” PEX to ceiling on 1st floor
• Cut and install PEX.

Mount shower drop ears using a pre-mounted Shower Valve Assembly.

• Prep: Attach drop ears to adapters. Use thread tape. Point adapters up.
• Attach one drop ear to 10” lumber, so faucet will be centered on the lumber. (before faucet attachment so faucet is not in the way of mounting the drop ears)
• Attach faucet to this adapter, and swing onto place to mark out location of second drop ear. If there is space, attach second drop ear, otherwise mark its location and attach without faucet in place.
• Mount faucet on both attached dropears to verify unstrained fit. Then take off the faucet. Prep work done, now to tub.
• Mark 6” separation in bath tub to drill 2 handle holes. Magic number is 4” for height of spout above tub rim, 28” above unfinished floor.
• This locates the drop ear separation fully. Now mount the 10” lumber-adapter assembly on the shower mounting block. This is now ready for final trim. Check that the faucet still goes on easily, and check also whether both faucets go on easily (replacability of parts)

10” 2x4

Get rid of stud so valve Pre-mounting Block is a single block. Recess Pre-mounting Block so that Shower Valve Assembly can be mounted directly on it.
