Re: PVC plumbing tricks

there are a variety of hdpe pipes and there are pipes of this type made specifically for water heaters or at least will be exposed to hot water.

try to visit your favorite hardware and ask for these new technology in pipes..not really new since they have been around for about a decade.

price of pipes isnt really that expensive but the fittings...yes the fittings..oh gosh!

Re: PVC plumbing tricks

i am not sure if the blue pipes like Neltex can be used for water heaters...id prefer GI pipes in the first place..schedule 40...but it seems the pipe threading is a dying trade..and so they came up with this new tech.

good luck on your project! please show some pictures as we love pictures here..pictures dont have to be taken by a digital slr as long as you can highlight what you mean.

perhaps you can use some editing software (i am using photoscape, free and downloadable) so you can resize and crop your shots.

cheers!

@ding,

Hahaha! 😀 (laughing at myself, not at your post)

While typing that reply, I was thinking: "I'm going to hear something from Ding about this."

I apologize for implying that your water is unsafe for drinking. Fact is, I do drink it
straight from the faucet. We buy filtered water kasi maselan si SWMBO (we have arguments about that every once and a while).

My point was the GI fitting at the end of the PVC pipe won't be introducing that much contaminants.

Thank you for keeping us informed :thanks: and again my apologies.

Sorry, Joey, for being to anal about this. Guess my response came on too strong. Brought about, probably by my passion for work and concern for all those plastic water bottles choking our environment.

and why so many diggings here and there...especially on the Guadalupe/Boni Edsa area? and another the perennial traffic between the c5 east service road till tesda due to maynilad ongoing (decade long) construction. Can you make it perfect the first time?

i just wish the future pipes are elevated instead of burying them to the ground.

Can't speak for Maynilad but, for the Manila Water area, there are 4000km of pipeline that needed to be replaced. We're at the tail-enf of that now. But next are sewer lines. We have, today only 26% coverage so more work. Really, we're just trying to catch up with years of infrastructure backlog.

On getting it right first time. We usually do (excellent track record, in fact). But let me explain. Laying a pipe requires many days of work each segment, we excavate, lay, test (physical, chemical, bacteriological), then restore (concrete/asphalt). In order to make the road passable to motorists, we usually work at night. At the break of dawn, we backfill the trenches with temporary material, in many cases, using asphalt so the road becomes passable for day-motorists. At night, when we continue the work, we reexcavate our temporary cover. This cycle goes on until the pipe laying is complete. What many people think is that we're so inefficient that we already completed the restoration then we dig it all up again, thinking we screwed up somewhere. When we finish the pipe laying, we restore in most cases using the more expensive 3-day concrete to minimize barricaded curing. Hope this clarifies.

But i do appreciate if you could let me know of any roadwork problems you see on Manila Water. We will solve it.

include me too for thinking that way..

now it is loud and clear.

and yes i wonder how in the world can they make a new concrete laid only days ago passable to bus and trucks?

hmmm..can you tell us the formula? hehe

thanks for the info bro.

Re: PVC plumbing tricks

Mga sirs and mam is it safe to get water to be used for cooking if the material used in joining my PVC blue pipe is Solvent and are all blue pipes lead free? and BPA free? some areas of my blue pipe kasi joined by solvent is exposed to the heat of the sun rays.

Re: PVC plumbing tricks

@ mchammer,

HI THERE AGAIN BRO, Yes it is safe and the pvc solvent dries immediately when two pipes are ajoined. No need to worry about its contamination, hindi naman sa loob ng entire pipe ilinalagay ang pangdikit, sa mga dulo lang ng pvc pipes. And I supposed the company manufacturing this pvc solvents have experimented on it extensively for many years before putting it out on the market.

Re: PVC plumbing tricks

Found this site just now:
http://www.ppfahome.org/pvc/faqpvc.html

What are the temperature limitations of PVC pipe?
The maximum use temperature for PVC pressure pipe is 140 degrees F. PVC DWV piping readily withstands the hot and cold water discharges that are normally associated with plumbing fixtures.

Can PVC pipe be exposed to the sun?
PVC does not readily degrade when exposed to sunlight (ultraviolet radiation) due to natural UV inhibitors present in the material. Short-term exposure to sunlight, such as during construction, is typically not a problem for PVC pipe. PVC piping may be used in outodoor applications when the piping system is painted with a light-colored water based acrylic or latex paint that is chemically compatible with PVC. When painted, the effects of UV exposure are significantly reduced.

Does long term exposure to sunlight degrade exposed PVC pipes?
PVC pipe contains stabilizers to protect the pipe against attack by UV present in sunlight. After several months of outdoor exposure a discoloration may appear on the surface of the pipe, however, the performance of the pipe is not affected. After two years of exposure, there is only a slight reduction in the impact resistance of the material. PVC pipe used in permanent outdoor exposures should be protected by a light colored compatible water based paint. Do not use oil based paints.

I hate plastic, too! I always use a reusable cloth bag for our groceries (yes, DIY din ako sa grocery 😀 ).

@ joey81

I'm glad you found that site,
Great information and reading materials bro, very informative and enlightening.

I'm glad you've mentioned roadwork complaints.

I saw a sign at the site in front of Sta. Lucia Mall explaining that the asphalt is temporary and the permanent concrete paving will be laid down after the leak tests are done. J.V. Angeles is the contractor and they're OK generally. They do the work at night and clear up the road in the morning.

But I think they screwed up yesterday. On my way home early evening, I was stuck for 1.5 hours in traffic from Karangalan to Makro Cainta. I turns out they were doing "emergency repair" (according to the one who answered the MW hotline) in front of Makro. They didn't have anyone directing vehicle traffic. And no, the traffic jam wasn't because of the heavy rains because I was already stuck before the rain fell.

Re: PVC plumbing tricks

mga Sirs thanks sa info, so thats it i'll put latex paint na lng sa blue pipes and fittings ko na exposed sa sunlight. to reduce the "cooking" of my pipes esp. the fittings where the solvent is placed. I hate using chemicals ksi esp. kung ginagamit at pinapasok eto sa katawan ng ta-o lalo na ang solvent. feeling ko kasi pang na expose sa init parang niluluto nya rin ang solvent kasama sa tubig. another thing when the pipe is hot sometimes I smell rust due to the gi pipes that is installed sa lines ko, which is bad. if I have the money papalitan ko eto ng HDPE pipes where in no solvent is involved. and place water water housing with filter para ma sala ung rust.
san kayang store mka buy ng HDPE pipes na mura? hehe.. thnx

Re: PVC plumbing tricks

MChammer, you should try PPR3 pipes. Cheap but good ones are Ariete and ERA. Get the white ones.

I am now looking for a suitable software for managing the plumbing business. There is a business software managemart but I still have not figured out all the nuances. Anyone, who uses it, could you tell whether this application has a built-in calendar so it is possible to keep track of your orders / meetings? I would like to report when my plumbing services will be available, and that the software does all the work for me - simple rules created using simple settings.
