We are asked to troubleshoot a hot water line of a residence. Hot water is supplied from a overhead solar water heater. Problem reported was "low water pressure even with new booster pump installed".

We cut the inlet pipe of the solar water heater and found out the problem.

One common mistake of newbie on PPR

Too much heating time and wrong insert depth.

Please follow PPR manufacturer specified heating time and insert depth.

Before venturing into the PPR system, I tried my best to get as much data regarding installation and advantages of using this system.
I believe my mistake was wehn I decided to make use of the 1/2" "HOT" pipe instead of the "COLD" pipe...throughout the entire set up.
Both pipes have the same outer diameter but the hot pipe has significantly smaller inner diameter which makes the pressure dropped significantly.
We haven't done anything yet but I am planning to remove the 1/2" pipe from the water meter and reduce it to 3/4" for the branches and 1/2" to feed the faucets.
Sana nakontak na kita dati pa! huhuhu...

Btw, the data I read on these PPR pipes did not mention anything about what you told me thru sms...perhaps, that's the most important tip one should bear in mind especially when there is a considerable length of pipe involved. We have consumed about 18 pieces of pipes throughout the entire house..hindi pa kasama yung hindi na namin pinalitan kasi wala naman leak (about 30 meters).

Magastos siya pero quick process pero dapat no back job like ours.

btw, we used Belden pipes and the fusion machine is made by Unitec. Very simple to use and a 200 peso cheap but functional pipe cutter.
I think i was a woodworker in my previous life...and the life previous to that.

We are constructing an extension of our house and I want to use PPR pipes for this extension house.
For example there is an existing PVC pipes, how will the PPR be integrated to the system?

use a female coupler with thread on the pvc system and use a threaded male adaptor from the ppr side.

Im using Belden PPR pipe by Unitec. Vesbo is also a good brand.

I have a bad experience with those china made PPR fittings bumibitaw yun threaded parts sa PPR material.

and if i may add..i once bought a china made ppr gate valve then it wont really close...water still can pass thru...bigla mag loose thread at the closing end kaya ibabalik ko pa uli yung knob counterclockwise to seat the valve to close it.

yeah, please use the same brand for the entire system and i also trust Unitec.

Medyo hassle pag nabili mo china made. Tapos meron problem yun mga fittings tulad ng experience ni Doc V.

Medyo mahal yun fittings na meron thread pati yun gate valve na PPR. Pag naweld mo na yun PPR gate valve then saka mo lang malaman na defective pag tinesting mo. I doubt na papayag yun hardware na binilihan mo lalo na pag china made.

I think Belden PPR Pipes are locally made by Unitec.
