Is there any pvc pipe out there better than copper to withstand hot water for solar water heater?

May I know how to check the pipe?

better as - not sure. but i use polybutelene pipes. no creeping and very good so far (6 yrs+). zero complaints and high temp & pressure resistance.

Copper is a good heat conductor, it dissipate the heat to the wall and you can feel the wall very warm. That's why seeking for alternative. How's the price for polybutelene pipes. Last i checked copper pipe 20' length = rm85.

i dont know the current price. tube is cheaper (a lot) than copper, cupplings are similarly priced. can check with a dealer. PB insulates quite OK. for our house we used PB for water and coppe for the gas piping.

Mine is single storey.

I dont use water heater lor... Currently the arrangement is like this: 1 tank serve 1 bathroom and another 1 tank serving 2 bathroom. I also have 1 bathroom with direct supply. (3 bathroom supplied from water tank while 1 bathroom direct).

Due to low pressure, i cannot use the rain shower type as the water wont flow out. I just can use the normal shower rose. so sad.

Should have read this forum earlier. I think I did my renovation all wrong! I used ABS thinking that it is a better material and used copper for my hot water(DIY solar heater). Should have just used PVC all the way and would have saved me a lot of money, pressure of water isn't high.

Nonetheless, copper is a lot easier to work with.

I'm planning a 1 Hp pump from water tank. What sort of piping should I use?

Stainless steel pipe was much better for last longer then were using PVC pipe of the interior pipe can easily clogging like jelly else.

But using pump can help up to clean interior pipe as well, cause the water pressure maybe runing more stronger.

If it is just cold water, normal PVC pipe will do, you can opt for thicker one also.
But if there is solar heater or heater storage , then may consider polyurethane pipe.

Stainless steel would be considerably more expensive rite? For hot water in planning to use copper pipe. But is there a concern pvc pipe joins can't take the pressure from the pump?

you can opt for polypipe by kindratech and use compression fitting

works very well for me..

i opt for polypipe with "thick" walls not those cheap not SIRIM certified..
and use Hansen fittings (http://www.sansico.com.my/)

redid my whole hse pipe to poly.. from the old metal type..

how is the cost comparison va pvc pipes? May I know how much did it cost to do up your house?

cost negligible, cause i DIY.. old hse.. piping runs on the outside..

bathroom do like how they run PVC didn't have.. save alot of money...

Skilful man. Do u need any special tools for it?

Yup, both stainless steel and copper pipe is expensive. It is also hard to work with, the plumber will charge more because difficult to turn the steel/copper pipe around, need to cut and install elbows, PVC also need to install elbows, just that it is easier to glue and cut. PU pipe is easier to work with, need only the clamping tool.

PVC pipe joins have no problem handling the pressure, just make sure you use the correct thickness.

By the way stainless steel/copper pipe may have knocking sound when working with pump.

So my contractor reccomends me to use abs class 16 pipe for incoming water throughout the house. How is the cost compared to poly pipes? Should I ask him to go with poly?

when i want to install water pump , my plumber advise me to change all existing to coppe pipe..

damn now i got problem , i dont recall my existing piping is anything better ..house renove almost ready and now i need to do plumping...

No need la.
My factory uses pump that provides up to 10 bar also using PVC pipes.
If joint correctly, PVC is just as strong.

Any sifu here can share where to buy 4 way and 5 way PVC fittings / connectors in Klang Valley.
