You used the WRONG plastic - should have used PEX, not glued plastic for water supply line in a home !
-If it was my home I'd remove it and replace with PEX.
If you don't you may have to run water through for about a month to get rid of that taste.
Copper can rust
To improve the taste of a water bladder that tastes like plastic, try cleaning it with a mixture of water and baking soda, or using a commercial cleaning solution designed for hydration systems. Additionally, letting the bladder air out and using it regularly can help reduce the plastic taste over time.
Copper or plastic piping
Insulators: wood, plastic Conductors: Copper, Gold
Replace them with copper or plastic pipe.
No, it is made for water only. Black iron pipe or copper are only allowed and a special plastic coated copper for underground installations.
all hardware stores sell adaptors to change from copper to plastic. You solder the adaptor to the copper pipe and attach the plastic pipe to this adaptor using screw clamps to tighten the plastic pipe on the adaptor. To be honest. This answer seems like a bush plumbers answer. To be technically correct. In order for you to connect plastic piping to copper piping one fitting is used and it is called a conex fitting, otherwise called cxc fitting. It has a nut and ring on either side of the joint and this type of fitting can be used on either copper or plastic making it ideal. As you tighten the nut the ring inside tightens onto either the plastic or copper making a water tight connection. It is said above that soldering a copper joint and then attaching it to the plastic pipe is the way but in my experience if you try do that, the heat from the soldering will melt the plastic pipe. Take the safer route and more professional route and use conex fittings.
It was really copper, but over time, the salt water got to it and turned it green.
Pvc, Wirsbo, Copper, galvenized, pex, or Polyethylene
Copper can be changed back into a solid by cooling it down, either by letting it reach ambient temperature or by using a cooling agent like water or liquid nitrogen to speed up the process. As copper cools down, its molecules slow and arrange themselves into a solid crystalline structure, resulting in the formation of a solid piece of copper.
aluminum foil, dime, coper wire, penny, water
The only sensible fix is to remove all plastic lines and replace with PEX, as should have been used in first place. PEX costs only marginally more than cheap plastics and will outlast them by years. Technique is different, you need a PEX coupling kit, about $27 including crimper, in Home Depot, whatever fittings were needed before will now be needed in PEX brass fittings. Attach to copper with 'Sharkbite' couplings.
