Sizing of Water Supply Pipe | Revised National Plumbing Code of the Philippines 

Thank you sir. I'm from Cebu, a graduating mechanical engineering student. That topic was not introduce to us. I've learned a lot from you. I suggest sir that you make a tutorial for plumbing system having a shower with cold and hot water system. That would be nice and I would like to learn it from you. I hope you will notice this comment. Pareha rata bisaya sir hehe. Hinaot ko mapasidunggan nimo ako hangyo hihi since nagka interest nako gamay aning plumbing system.

Sir yung 2 storey sa last part, clarrification po, img 38mmØ is equivalent to 1-1/2"Ø for Bldg and Service Supply. Thge topic is very informative, thank you

Maganda po ung tutorial nnyo very informative ung last lng na 38mm sumabit ung 38mm hinde nmn 3/4" bka namadali lng pero maganda ang tutorial nnyo very clear..

Tingin ko mahirap gamitin ang table for given pressure since hindi lahat searchable ang pressure ng mga water concessionaire. Pero ayos ang tutorial thumbs up!

Thank you so much!! You are better than my professor!!

Thank you, sir! Sobrang helpful

Correction lang po to conversions, 13mm is 1/2'' and 38mm is 1 1/2''

Sir, correction, 13 mm is not 1/4 but 1/2 in.

Thank you for this video. Kindly consider Sizing a water supply pipe for let's say two storey building so we have learnt further from it. Thanks

nahirapan sa kalisod Sir. hahah salamat kaau sa vids nimu daku kaau tabang.

It helps me a lot to design my new project! Many many thanks Engr.

Thank you for this lesson sir. It helps a lot for my review of RMP

Sir thank you po at malaking tulong siya sa pag design

very good explaination sir thanks

More of plumbing problems like this thanks

Ang fittings po ba mas malaki kaysa sa pipes? Or same size lng po? BTW, very informative videos lodi

dakoa nimo ug tabang sa akua engr. Godbless. deserve my Subcribe and likes! more videos to upload po.

Thanks Engineer, may konting Question lang po Kapag Downfeed system po yung gamit na design ng water supply: Water main --> Cistern tank --> Pump --> Overhead tank --> distribute to lower floors. Tapos Gamit po yung formula nyo, yung parameter po na pipe length (water main to most remote fixture) hanggang saan po ba sya susukatin? most remote fixture in the ground floor? or most remote fixture in the highest floor habang dumadaan sa Cistern tank, pump, water tank, tapos pinakamataas na floor at pinaka dulo na CR. Kasi po sa example 3 na 2 storey, given na agad yung length ng pipe pero hindi ko alam pano or hanggang saan sinukat, kung dumaan ba sya sa tanke or upfeed system lang agad. patulong po hehe thank you!

thanks sir! highly informative

for Pressure, what do we do if the pressure achieved is negative due to very little ave. pressure in metro manila which is 7psi as per google

thank you sir sa video nyo, very informative.

kakapanood ko lang po ng video mupwede gawa ka din ng sa sanitary sir? sa plumbing po. maraming salamat

Hi sir, salamat sa video and its very useful imoa tutorial, asa ang link for water supply system na video? Salamat

thank you so much!! more power!!

Good morning sir. Matanong ko lang po ano ideal size ng ppr going to cistern tank(15.cu.m)

what is the standard water pipe size in households in the Philippines?

Sir tga davao ka? Master plumber ka? Dawat kag consultation medyo highrise xa 13th storey..

sir ask ko lang in my on going project naka encounter ako ng riser pipes for cold water line na sa ground floor ang size is 50 and then pag akyat niya ng 2nd floor nag reduce siya from 50mm-40mm is paano? po siya ma explain or what is the possible explanation for that thanks po sa ans.

Tanong sir paano kng below na sa table pressure range 207 kpa like 198kpa na xa wla na sa table ano ang gagawin na option?

Malaking tulong po. Salamat!!!

Hai Sir. May video na din po ba kayo ng Sizing for storm and drainage system?

Pls , Make the VDO about how to calculate hot water demand in building and sizing of hot water heater also

Thank you po, napakalaking tulong sa design.

Engineer. Pwedi po pa clarify about sa definition sa length po na ginamit. Paano po i measure? Is it total length?

Goodmorning po. Kung example 2 storey na bahay ilan po ang magiging static pressure?

Good morning, Engineer. Ask ko lang po kung ano po mas ok na fixture for waterline pag laundry shop? Laundry tub po ba or hose bibb nalang? At pag laundry tub po, nakalagay po kasi sa table namin na "each pair of faucet", so dalawang faucet po ba ibig sabihin non? Sana po masagot nyo. Thank you po!!

Hi Sir. What is the water pressure from an overhead tank 10 feet above ground. Thanks.

boss tanung ko lang, sa pag layout ba ng mga pipe sa wall, may standard din ba na nakasaad sa code?

is the service pipe and branches in diameter po ba sir?, I hope you find this message well po

Sir, saan po makikita ung fixture unit table nyo? Hinde po ba 6units per water closet ayon sa book ni max fajardo?

38 mm = 1-1/2 inches po, sa may bandang dulo ng video. 😊

Sir,,Nice....meron ba part 2?

Thankyou ang laking tulong!

Sir somewhere sa video sinabi mo na balikan yung water system module. san po yun makikita sir?

Good day po sir, ask ko lang po if hanggang saan mo ang maxmimum allowabe lenght ng pipe ? Yung sa loob lang po ba yun ng building o hanggang sa water meter po? sana masagot po salamat

Is it the same procedure for high rise buildings?

Thank you so much!

Salamat sa bagong kaalaman, new subscriber here, I already watched your video sana madalaw mo rin ako sa aking tyanel salamat po

what is the water demand for the commercial building? does is stop sa wsfu lang?

thank you po, sir!

salamat po engineer. galing nyo po magturo, God bless po. ask ko lang po panu ung value ng Length of pipe kapag paliko liko and two storey? ang susukatin pa rin po ba is ung pinakamalayong fixture sa ground floor mula sa water source?

hi sir meron po ba kayo sa storm

anung code po makikita ung 8gpm na ginamit ninyo sir sa WSFU equivalent or conversion to gpm?

Sir my estimate po ba kayo sa labor cost lang ng plumbing works? Salamat

Sir pagnakuha ko na po yung total demand in GPM, ilang HP po kayo yung pump motor ko

paano po mag compute yung volume ng water tank na dapat gamitin sa admin building

san po galing ang 1FU = 7.5 GPM ano pong reference neto?

Ano po gamit niyo po na waterline pipe? Hdpe po? Tsaka yung mga fittings po?

Sir nindot imong explanation.

Question lang po regarding sa 8gpm na multiplier. Anong basis po yan?

Ang ganda ng video mo master.

thank you sir, still hoping po for High rise building sample

May instance po ba na pwedeng mas malaki yung Branch pipe sa Service pipe sir? Thank you po

Can you make a tutorial if it is an overhead tank in a multi story say 6 stories.

hindi po ba ititimes yung 3 meters sa 2 kasi 2 storey po siya? thank u!

thanks

What if below 30 psi po?

hello po sir, papano po pag water tank?

QUESTION po ano kaibahan ng F.U and WSFU kasi iba ang equivalent value nila san po applicable na gamitin ang 1FU = 7.5 gpm while 1 WSFU = 1gpm pasagot po thanks

Super. Salamat.

sir what if the pressure in the main water line is under 30 psi?

Also 38mm =11/2" sir.

why it is not applicable to use the value with an asterisk sign ?

paano po nman eh solve ang maximum probable flow rate?

Ask lang ko sir, Di ba 12 ang Total sa WSFU? Dili 6? 😁 Correct me if I’m x ha, nag ask lang pd ko hehe

sir paano po calculation kung naka sub meter po thanks

13mm = 1/2” 38mm = 1 1/2”

ask ko lng po. talaga bang pag one storey is 0, pag 2 storeys is 3? ksi pag 2 storeys usually nasa 6 meters ang height.

Sir ask ko lamang for confirmation 3/4" is 38mm? but 25mm is already 1" in diameter.

Hello Po, Good Morning. I would like to ask lang, if 1 FU is really equal to 7.5 gal/min? San Po makikita Yung part na iyan sa Plumbing Code? Thank you po Kung Sino man mag reply. ~

38mm = 3/4"?

In example #3, how did you get the 320Kpa?

Hello, may I ask? What if the length of the pipe is not given?

sir diba pho 38mm=1 1/2 last part ng video,..

Plz shear tables in pdf

Engineer! Aware po ba kayong itong certain video mo is ninakaw and nireupload ng isang TUBERO VLOGGER AM TV? ginamitan lang ng voice changer yung boses niyo, Pero nakakabastos parin kung iisipin na pinaghirapan mo pero ginagamit lang ng iba, "sizing of water suplly." ang video title niya.

mali naman conversion mo ng mm to inches.

Engineer,, English please

can u give us the WFU table?
