Uponor Pex Repipe – The World’s First, Best, And Most Widely Used System For Single Family Homes And Residential Units.

What is PEX?

PEX is an acronym for crosslinked polyethylene. It is a flexible, durable, proven piping product that has been used in plumbing systems for more than 20 years. PEX tubing won’t pit, scale or corrode and, because of its flexibility, it also offers potential freeze-damage protection.

Uponor Pex plumbing systems feature PEX-a tubing, which is considered the superior PEX tubing manufacturing method in the industry. PEX-a is the most flexible of all PEX types, and because of its shape and thermal memory, it can use ProPEX expansion fittings which are the only fitting system that actually gets stronger over time – making it highly leak resistant.

1) Repiping in a home begins at the transition point.

2) The transition point is the point where the potable water system enters the building from the exterior of the building.

3) Repiping a potable water system means you totally abandon the existing potable system and replace it with a new system.

4) The first step in repiping your home is masking or “covering” the floors, and this must be completed before the walls are masked off. This overlap “ enveloped ” system allows the plastic sheeting to be rolled up in one continuous motion.

5) Cutting the sheetrock: You will be shocked at how little sheetrock has to be removed for the layout and installation of a new potable water system. A real Pex Plumber is an expert at HVAC, framing, plumbing, and electrical layout, and will lay out the home pex repipe in the most effective route. The better the repiper. the smaller and fewer the drywall holes!

6) A “GREEN REPIPE” potable water system refers to a Pex repipe potable system only – such as UPONOR or ZURN with corrosion resistant fittings. CPVC and copper systems are not green systems.

7) The drywall pieces that are removed must be used in the patching process as each texture is a little different in thickness. This gives you a uniform surface thickness as you start the repair process. Each piece goes back in the hole it came from.

8) Repipe with an approved material. There are currently three main materials used in pex repiping jobs across the US: copper pipe and fittings, CPVC pipe and fittings, and PEX repipe and fittings. (DO NOT USE CPVC, IT IS THE NEXT POLYBUTYLENE)

9) Repipe inspections must be performed by the local building inspectors after the repipe is completed, with the system under full water pressure.

10) The signed inspection card must be given to the homeowner after the PEX repipe inspection is completed.

11) Drywall repair begins after all the necessary backing has been installed. Backing supports the drywall pieces that were removed to access the potable water pipes and accommodate the repiping of a new Pex repipe or copper potable water system.

12) The fiberglass mesh tape must be used 100% of the time.

13) The patches must be pre-filled with quick set patching compound. The compound comes in 18lb bags, and because it is a powder, it must be mixed with water. This locks the perimeter of each patch and will make the area of the patch stronger than it was before the work process began. The reason this is important is that when you close the doors in the house, the walls flex just a little bit, and if you do not perform this method of repair, the patch will fracture over time from the flex/vibration caused by shutting the doors.

14) Do not coat the drywall patches with regular all-purpose joint compound on the repipe patches.This is a common practice and the patches will crack later 100% of the time, even if it’s years later.

15) Coat all the repipe drywall patches with quick set patching compound only. USG will do and you can find it at any home and hardware store, or you will have fractures in the walls at the patch locations.

16) Float all the walls with quick set patching compound and use a 12″ drywall knife and stagger each coat until the walls become smooth and flat. The next step is wet sanding the patches and this must be done if you want the patches to blend in perfectly after the texture is applied. The reason you’ve seen bad patches in the past is that repairmen do not know how to “kill the edges.” This is an old drywall term that means you must do the detail wet sanding work and there is no short cut.

17) Texture to match the existing texture, and this is not as easy as you might think. This is a real art form for the few that know what they are doing. Also, if the texture is spray texture, you must sponge off the overspray for the texture to match. Nothing gives away the location of a patch more than overspray that is painted over and not “killing the edges.”

18) Paint to match the existing paint. All repipe companies color match the same way. They run down to their local hardware store and have the computer color matching done by the man behind the counter. This is beginner color matching. The proper way to color match is hand color matching. First, match the paint sheen. Second, computer match for the base color. Third, tint for color adjustment. Fourth, match the color and sheen after the paint sample has dried. Repeat if necessary. Did you know that the paint color on the wall after it dries will be different than the paint color while it is wet and in the can?

19) If you follow the basic repiping rules, after a very short time you will not be able to point out all the drywall patches from the repair. You will simply forget where the holes were due to the patches receiving the proper floating, texture and painting techniques. Your friends, neighbors, relatives, and even plumbing contractors will not be able to find the patches.

20) This is a basic guideline for a home repipe. and if done, properly you will have a repipe that was done as well as a repipe can be done.

Broadband DSL and ADSL Internet Access Technology – ISPreview UK #dsl,adsl,sdsl,vdsl,adsl2,digital #subscriber


Broadband ISP Technology

DSL (Digital Subscriber Line ) is a common technology for bringing high-bandwidth (broadband) information to homes and small businesses over standard (copper) telephone lines. DSL comes in many different flavours, such as SDSL and ADSL2. The most common forms of DSL in the UK, ADSL (Asymmetric DSL) and ADSL2+, splits a single telephone line into separate voice and data channels, allowing you to make a phone call while surfing the Internet at the same time.

ADSL offers speeds of up to 8Mbps (Megabits per second) downstream and 448Kbps upstream (832Kbps on business lines). The technology is cheap, fast and easy to install (doesn’t require an engineer) and reasonably reliable, although performance can suffer due to ISP congestion, distance from the local exchange (shorter lines are faster but anything over 6.5km is usually slow), poor home wiring and interference from other electrical devices. Each connection is fixed to a specific telephone line.

The latest ADSL2+ (ITU G.992.5 ) technology is capable of pushing download speeds at up to 24Mbps and uploads at up to 1.4Mbps, it also supports port bonding (linking several lines together for faster speeds) and has an improved range over ADSL. Both ADSL and ADSL2+ are “best efforts ” broadband services, which means that bandwidth is shared between many users and can be highly variable – especially over long distances and at off-peak times (i.e. busy afternoons will slow the performance). The following graph shows what impact distance can have on speeds.

Users of these services should learn to understand common router statistics, which can help in diagnosing line problems. Figures for the following items will change depending on your line condition (e.g. expect them to be worse during thunderstorms that will cause extra interference):

ADSL/ADSL2+ Router Terms and Statistics

* Line Profile / Sync Speed

This is the speed (usually in Kbps) at which your router connects to the local telephone exchange. The actual performance of your line will usually be around 20% less than this, possibly even lower due to ISP-side limits or environmental factors (e.g. interference from Christmas tree lights, microwaves and AC adaptors).

High attenuation usually means you live further from your local exchange, thus lower is better (e.g. an attenuation of 60dB might give you a best speed of around 2Mbps).

* SNR / Signal to Noise Ratio (dB)

A high SNR usually means that faster speeds are possible and upgrading to a faster connection will often cause the SNR to drop. SNR can be improved by installing a special filtered faceplate on the line, such as BT’s iPlate (Broadband Accelerator) device (not to be confused with Splitters / MicroFilters).

Related to the SNR above, an SNR Margin is a measure of the difference between your current SNR and the SNR that is required to keep a reliable connection speed. SNR Margins tend to range from around 6db to 12db, with higher being better. The figure will fluctuate during the day, especially at peak times. Note that significant fluctuations (e.g. going from 8db to 4db) may cause connection problems. It is sometimes possible to tweak this figure and keep it higher, depending on what make of router you have. Using your homes mastersocket for the broadband router is also helpful. Elsewhere some businesses still use Symmetric DSL (SDSL) technology, which is similar to HDSL via a single twisted-pair wire and can carry 1.544Mbps (U.S. and Canada) or 2.048Mbps (Europe) in each direction on a duplex line (the speed is the same in both directions). In addition, those looking for information on VDSL and VDSL2 (FTTC) services should look under our Hybrid-Fibre section above as this is somewhat of a mixed technology.

Furthermore BT has also introduced a special long-reach style of DSL called Broadband Enabling Technology (BET), which is based off Symmetric Hi-Speed Digital Subscriber Line (SHDSL). This is designed to deliver speeds of up to 2Mbps into rural areas that can reside up to 12km away from their local telephone exchange, where normal DSL services would fail. But this method is extremely expensive (costing up to 1,094 +vat to install), poorly supported by ISPs and requires two phone lines (twisted pairs) to achieve the best performance.
