Back to the 120 injector. I don't think the one advertised as 130, was. Mr Kerry may deliver a 10 heat range NGK plug today so will see if that is the cure.

Korea. The country has Seoul. But the cars don't.

If I may. the problem is old GRUMPY men logging onto AN at 9 am and complaining about everything in Thailand. ????

^ So we are down to 11gpm with the shower heater still requiring only 1.5 gpm.

Apparently not and I checked I am not confusing you with anyone else. As stated before a shower heater with an integral booster pump requires 1 psi of positive pressure to switch on. Not 1 bar. The size of the pipe in a shower heater is about 1/4 to 3/8in. The pipework in a house is usually 1 in or maybe 3/4. There is no way a flow though a shower heater at about 1.5 gpm will effect the pressure in a 3/4 to 1in pipe. A 1 in pipe at 1 psi at the open end has the potential to flow about 20 gpm. The 1.5 gpm required for the shower heater will not create a reduction in that 1psi. No matter how hard you try to believe it. You haven't grasped the non magnitude of the problem you are inventing. I believe you are confusing a pump that would supply the whole house with a tiny booster pump in one appliance. As for a cavalier attitude to the safety of others. There is no safety issue here at all. If the OP installs a water heater with a small integral pump he will not create any reduction in the pressure in his supply piping to his house. He will not increase the flow in the 1 inch pipe by the 1.5 gpm required by the heater increasing the demand to 21.5 gpm. The potential flow in the 1 inch pipe will still be 18.5 gpm or a positive pressure of about 0.8 PSI but positive non the less and sufficient for the heater. Min requirement of the shower heater is 0.7 psi

For the curious and search engine friendly I found at least two tour companies in CM who offer a downhill cycling tour. Get driven to the top and cycle down Maybe there are too many cyclists for the road to safely handle.????

Will you find a link to said regulation. I can't find it. It does not appear to be on the PWA site. It is possible that the OP drives occasionally over the limit or pops down to the 7- Eleven without a helmet. All breaking the law. He might even buy alcohol from a village shop between 2pm and 5pm.???????? I don't think you fully comprehend that the supply line must be at a positive pressure for the shower heater to operate. I also don't think you have any knowledge of hydraulics or fluid dynamics. Just keep harping on about a bucket in the toilet. Which by the way needs negative pressure for the flow to reverse not the positive pressure required for the shower heater to switch on. The OP is free to do whatever he sees fit.

Of course you can. Nothing to stop you and nothing bad will happen. You will simply have a constant quality shower.

Or As I suspect. The errant cyclists get driven up there and freewheel down????

You are not allowed to ride down. So simple logic says you cannot ride up as you can't come down. Seems simple to me.

Use one of these and you can also tell how far away they are????

^ It is about a shower heater.????????

Yes but if in the example shown the neighbour doesn't have a check valve. ????

A note to the OP. Take no heed of all this pontificator about pumping water. Whichever shower heater you find with an internal booster pump will work just fine.

A lot of you guys are not thinking this through or maybe not thinking just reacting. May I explain for the technically challenged???? Many houses in Thailand have shower heaters. If you turn off the water supply to the house and open the valve to the shower heater it will not switch on. Why? The shower heater requires positive pressure in the supply line before it switches on. If the shower heater in question has a booster pump to give an adequate flow at the shower head, it still requires a positive pressure at the inlet before it will switch on.. Thus the pressure in the line supplying the shower heater must always be positive, about 1 psi. There is no suction taking place so there will be no potential for ingress of germs into the supply pipe.

No. Not if the potential water supply to the shower heater is greater than the shower head flow. A 1" pipe under gravity will supply 16 gpm (3/4 pipe 11 gpm) and the shower unit requires a minimum of 1 psi of positive pressure to operate.

I believe Buffalo is renowned as being the snow capital of the US, So nothing new there then????
