    He may be thinking of too hot for standard pvc piping, in which case he is right.
    Otherwise I wouldn't bother too much when a Thai says "too hot", they are used to cold water and anything warmer is "too hot".

    You ought to get a plumber for doing the piping, the sparkys job is only to connect a few wires and a sparky is usually not familiar with hot water plumbing.
    Speak to the aircon installer/serviceman, he usually does hot water plumbing as well.

    I suppose you should not use the blue pipe for hot water, although I have used it for years in some places without problem

    it all depends on how hot the water gets

    Thanks for the advice. Our spark is an air-con serviceman!

    He specifically meant the water in the shower would be too hot. I have explained to him that there should be an ajustable valve both in the cold water inlet to the heater ( a tap is fine) and also there is one in the mixer tap itself (aside from the taps which can alter the heat) so the flow of the hot water can be adjusted to suit.

    The excuses are now that he doesn't know how to plumb it so we have contacted another guy who does these types of installations. Fingers crossed. No problem to use copper piping at extra cost. If necessary that's what we will do.

    I specifically wanted a more powerful shower than the electric one we currently use with a hotter temperature. The added benefit is to have hot water in the kitchen sink for doing the dishes.

    Sure and it is not the pvc you have to worry about, it is the glued joints that goes first.

    That is what you shall use for hot water and that is also the reason why the aircon guy usually does these kinds of jobs.
    Same copper pipes, same gas soldering method, same isolation around the pipe.

    Forget the copper pipe. Use the hot water PVC (normally yellow in Thailand). As Lom notes, it uses a different glue that doesn't break down with hot water as does cold water PVC glue.

    Piping is done same as with any PVC. The most critical part of the plumbing will be in shower or tub where you have the output of the cold and hot water supply. If the distance between cold and hot water outlets is not the same as distance between mixer hot/cold in, you will not be able to mate the mixer to the pipes.

    Although there is a "standard" suggest you pick the mixer you want and look at spec for distance between hot/cold so piping will perfectly match.
    Whenever you find yourself on the side of the majority, it is time to pause and reflect.

    13.5cm if I remember correctly, but always get the mixer first and mark it out on the wall.

    Center to center, 13.5cm.
    Also the joiner is offset so can have upto around 2cm of play.

    Where do you buy the 15mm copper pipe and fittings in Chiang Mai Dr A? brought the odd pieces and copper elbows and compression fittings from the UK to do my shower.

    the one used in my place is "orange" and is marked on the outside of the tubing that it is for hot water use. only somewhat flexible.

    There are a couple of shops within the moat area, oldgit, almost opposite each other, near the moat and on the road from Chedi Luang to CM gate

    they sell mainly aircon but have racks of copper pipes of all sizes and lots of fittings inside

    sorry, I cannot remember exactly where they are located but ask around

    when I get back I will have to remember!
    I have reported your post

    Yep seems to be a fair amount of adjustment with 150cm the center.

    Just checked with a builder friend. He says, Home Shop not Home Mart. Global House doesn't have. Doubt you have a Home Shop in CM only in Roiet as far as I know. Owned by the brother of Global House.

    Suggest you try Home Pro in CM. Ask for PPR.

    thanks Norton, they have all sorts of shops with similar names

    yes, the shower fittings are usually on slightly eccentric moveable swivels, so the pipes do not have to be exactly in position

    you just have to make sure they are equally moved so the tap unit is level

    I bought my PPR at a HomeMart in Udon. It doesn't use glue. There's a heater tool that heats both the inside of the fitting and the outside of the pipe until they begin to flow a little and then the pieces are just shoved together. My HomeMart has the heaters available for rent. I used this system for the hot water when I built my house 2 years ago. I have a Grundfos pump at 50 PSI and haven't had any problems.

    We had real trouble getting someone to fit the shower, mixer tap and the water heater as no local Thais were familiar with similar systems.

    Luckily we asked where we bought the bathroom tiles in Hualamphong (near the train station in Bangkok) and they knew of someone and he has done a fairly good job.

    We went for a 250w electric pump to provide the water pressure, the Fagor multi-point instantaneous water heater and a combination of Starmark, Karat and Modona for the fittings including the shower heads, stem and mixer taps. The pressure is great but when the temperature is adjusted using the taps the hot water doesn't seem to be constant.

    Overall I am fairly happy; pressure and power are fine, heat is fine but there's no consistency in the temperature when the taps are adjusted.

    They also used steel pipe for the hot water, with steel fittings and the normal blue pvc for everything else.

    Has anyone died in the shower?

    This is our shower area with the rain shower. Floor tiles are going in today. We went with a slate grey colour for both the walls and the floor. The floor tiles are anti-slip and have a rough surface but will feel nice under the feet (hopefully!). They are 12"x12" by Cotto. The wall tiles are Vertigo Slate 8"x8" also by Cotto. They are being grouted tomorrow.

    Floor tiles.



    Shower attachment. Rain head is Modona, stem is Star Mark and the hand attachment is Globo by Karat Faucet.



    The mixer is Modona with modern cross style taps. Valve is Star Mark.



    The multi point water heater installation.



    Electric pump providing the pressure.

    Is this a heater which can provide hot water for multiple showers? Can you give us more information about brand and specifications?

    Many thanks in advance!
