Everything You Always Wanted to Know About PEX
Part 05– PEX and the Single Installer – My PEX installation experience part 2
- Much like pulling thick wire
- My method
- Used fish tape to pull mason's line
- Tied mason's line to PEX about 4 inches from end.
- Taped above & below with electrical tape
- Then tied line again closer to the end of PEX.
- Wrapped again with electrical tape
- Pull extra
- Unroll and let it lay straight for 24 hours if "curve memory" is a problem
- Can be challenging and require an individual installer to go back and forth between the feed point and the pull point.
- Supporting PEX
- 1" and smaller PEX must be supported horizontally every 32 inches
- Vertically, it must be supported at every floor and midway between floors (every 4-6 feet)
- Can be challenging to hold in place until secured
- Zip ties are your friend!
- Using a manifold
- Determine your needs
- Number of hot and cold outputs
- Valve type
- Find a location with
- Easy access
- Fairly central to avoid long delays for hot water
- Limited light exposure
- Build or buy?
- Securing manifold in place
- Anchor securely
- Block wall with anchors
- To wood for spanning wall studs (I don't know why I kept saying "Joist" during the recording)
- Do not anchor to drywall
- Insulate from wall if needed
- Connecting to the main line
- What to replace and what to use
- Size matters
- Plan to include manifold if needed
- Connecting to water heater
- Where/how to connect
- Pipe Unions?
- Protect from heat
- Shut-off valve
- Expansion tank
- Silicon tape or pipe dope
- Connecting to endpoints
- What to keep and what to replace
- Transition connectors
- Exterior hose taps
- Reuse or replace?
- Frost free / anti-siphon
- Anchor securely
- Help is better!
- Turning it on!
- If using a manifold turn on one section at a time, from the bottom up
- Open sink valves
- Ease it on a little at a time
- Then increase flow
- Turn off sink tap (Slowly) to let pressure build
- Keep watching for leaks
- Coordinate with a partner and communicate (cell phone?)
- Cover any PEX exposed to light
- Watch for leaks
- Repair holes
- Run water daily to flush out bad taste
