Sizing Water System Based on UPC 2018 Chapter 6

Күн бұрын

This is an instructional video on water sizing based on the 2018 Uniform Plumbing Code. This is the second sizing exercise I've done here on the channel. Water sizing for a residential plumbing structure is not as difficult as it may seem, and hopefully this helps. Please watch the video and if you any questions whatsoever feel free to ask! I will always answer questions.

OUTSTANDING video that really simplifies the domestic water sizing. It would really be helpful if you did a continuation of this video where: 1. You sized the water heater. 2. You sized a hot water recirculation system (including the pump) for this example. That would really help pull some of the other aspects of a Domestic water system together. Finally, are there any fundamental differences between sizing using UPC vs IPC (other than the page numbers of the charts/tables)? This is really an outstanding series of videos. Thanks again for clearing up some aspects of basic system design.

@BGsPlumbingClass 3 жыл бұрын

Water heater sizing is actually pretty basic when you get right to it. It is based on the first hour rating- the amount of water heated in the span of an hour, how many restrooms there are, and how many bedrooms. You'd think it would be based on something else [Table 501.1(2)].

Excellent teaching! I've been learning California Plumbing Code which base on UPC for a while. 2 questions here please, when I use table 610.4 to locate the supply branch's size, I always need to use the minimum pressure for the pressure range column? If the water pipes are below the meter(This video demonstrate all fixtures above the meter), do I need to still use the minimum water pressure minus the pressure loss of 0.5psi/feet or the pressure loss shall be always calculated by the highest outlet? Thank you very much!

You did the 23.5 then added the 5.5 but after the water heater towards the meter you have to add the dishwasher back into the total count in order to get the total to 31.5.

@scottadams364 2 жыл бұрын

Kind of, and I actually have a question about that. The units that weren't accounted for in the branch to the water heater are the CW and LS, because their cold water fed upstream of the water heater. So add those 5.5 to the 23.5 and you get 29 fixture units. The other 2.5 come from the hose bibb that's upstream and has no hot water. So, should that common line leading to the water heater actually be 29 fixture units and not 31.5, because it's beyond the feed to the hose bibb? It may be negligible, but in a different example/situation it might make a difference, so I'm wondering what's correct. Thanks!

@BGsPlumbingClass 2 жыл бұрын

@@scottadams364 If you look at the 34 minute mark, you'll see that 19.5 fixture units are required for the water heater. That is to say that if the hot were turned on to every fixture that uses hot water at the same time, enough volume must go through the heater to meet that demand. So, the clothes washer, laundry sink, etc has to be fed through that line as well as the cold supply upstream. This concept- and the hose bib concept- is probably the most confusing out of the whole process. Look at it as a different route to supply water to a fixture. Hope this helps clarify, if not reply again and I will try a different approach.

Hey Ben, one of your students here. Just watched this video and going to try to size out my parents’ cabin remodel here in Blount County. But hey, I guess I should see if IPC standards are different when it comes to supply line sizing… 🤷‍♂️ Speaking of, when you gonna switch over to IPC?? I think I know the answer there…

@BGsPlumbingClass Жыл бұрын

Daniel, there is a significant difference between the two codes- more than I expected for sure. The UPC is a much more detailed and specific code. I believe I mentioned to you earlier that IPC sizing is similar to Appendix A in the UPC. Also, I may have to switch to IPC, but my heart belongs to the UPC- forever.

Hi man here’s another question, does it matter what the piping material is (PEX or Sch. 40)…will it not affect the pipe sizes? Most of my projects are in Cali. What type of piping material should I use for outside (from water meter to house) and inside house?

@BGsPlumbingClass 2 жыл бұрын

The type of material used is going to be contingent on the local authority. Some don't allow PEX underground. I prefer a copper supply underground, however for larger diameter supplies I've used Sch 80 PVC as well as C900

@BGsPlumbingClass 2 жыл бұрын

Manholes for sewer lines on a property fall under section 719.6 of the 2018 UPC. It says they are not to exceed 300' apart, but must be approved by the authority having jurisdiction. A building sewer cleanout follows the same requirements as a building drain- 100' max, not to exceed 135 degrees. That is section 719.1

@jeremyransom759 Жыл бұрын

I wonder if it would make it easier to explain or understand the value of total FU on the section of pipe immediately upstream from the hot water heater tie-in as being equal to the total FU demand from the WH plus the total FU value from all fixtures downstream of the WH that use cold water only. In your example: WH demand= 19.5 FU+ 7.5 FU(WC 2.5FU x 3) + 3.5(HB1 2.5FU + HB2 1FU)= 30.5). Just a thought to hopefully make it easier to understand.

@BGsPlumbingClass Жыл бұрын

I really need to do a couple more of these examples. Also, since the codes are readjusting the way we size water systems, it is important that a new example be done. Look for it- eventually (gotta make time to do them).

@pauliancabasag3598 2 жыл бұрын

Hi man I am new to plumbing and would like to know more. So after you size every pipe of the house, in real life would you just choose the largest pipe from the meter and use that for all pipe size in the system instead of using different sizes from the calcs?

@BGsPlumbingClass 2 жыл бұрын

I'd run the recommended size. Without getting too technical, If you oversize then you will have a slower velocity and the possibility of any "solids" settling on the bottom of the pipe. That could result in the tubing developing a leak through corrosion from within.

The total developed length is the point from the meter (at curb typically) to the furthest point in the system itself. In other words, the furthest distance a drop of water has to travel from leaving the meter to dumping out of the piping- either through a hose bib, a shower, a kitchen faucet, etc.

I believe this footnote should also be in the UPC. "3 The listed fixture unit values represent their load on the cold-water building supply. The separate cold water and hot water fixture unit value for fixtures having both hot and cold-water connections shall be permitted to be each taken as three-quarter of the listed total value of the fixture."

Short answer is no. The fixture unit calculations were originally based on Hunter's curve and a "scientific" method of estimated occupancy. I believe you asked in reference to the curve in another question. So I will explain a bit in that question. But to this one, no the fixture unit value is not based on a gallon per minute basis- great question.

Good question Southlake. I had the same concern. When sizing the water main and water meter, use the full fixture value written on the fixture value chart in the code book for all fixtures... however when sizing separate interior hot or cold water line branches, the code says if a fixture has BOTH hot and cold going to it , you can reduce the listed fixture value by 25% or in other words figure the fixture at 75% of the fixture value listed on the chart in the code book. This can drastically change what size your interior water piping needs to be.

@amlars2000 4 ай бұрын

This video is good but a little misleading...the code states that we are to use the full fixure values listed in the UPC code book to size the cold water supply to the house as well as to size the meter, however, what the video is not telling you is that when sizing individual hot OR cold interior sections of water piping, you indeed can reduce the listed fixture value by 25% for any fixture that has both hot water and cold water going to it. In other words you can multiply the fixture unit by 75%. This can drastically reduce the sizes of different sections of your water system.....And you will not starve any of your fixtures of water by using this method as its in the code book.

@BGsPlumbingClass 4 ай бұрын

You are absolutely correct about the 75%, and on top of that, you could even size according to bathroom groups.
