Question about Water Heaters
When neighbours use a hot water tap the banging in my house is tremendous,it seems to come from the bathroom tap (neighbours) and when I use mine. the on/off switch (on mine) is a lever
Install air chamber to cushion sudden-stop of flowing water.
Water flow coming to sudden stop is called water hammer, and will bang pipes, but also loosen plumbing joints, causing leaks.
Air chamber has to be vertical, and about 18" long, with cap on top.
By code each Hot and Cold line at each tap will have air chamber located behind the wall. So there are two air chambers at each tap.
In your case, you can probably add air chamber to your Hot and Cold lines and solve problem for both dwellings.
Water hammer is caused because water does not compress like air.
So when long column of water suddenly stops... the whole pipe-full of water comes to sudden halt... and that water could weigh 1-1/2 pounds ... and just like a hammer head moving, the weight of water bangs the pipes to dissipate energy, causing noise.

Your check-valve has most likely failed at the switch.
The flow check valve works by opening when you turn the water tap. When it opens it closes a switch which turns on your heating elements. When this switch fails you will still have water flow, but no heat. Titan has parts for this but you will need to call their service Dept.

Testimonial: "Thank you so Much!!"
Some circulation pumps have a 3 phase mixing valve (cold,warm,hot) to regulate the water pressure in the building; no way to know unless you trace the plumbing. Basically, the hot water temperature could be lost because the circ-pump is cooling it with the cold water supplied to it. This is used to balance the pressure (aka Pressure Balancing Circ-Pump), so heater is really working overtime to heat the water. If the pump has two in and one out that's more than likely your problem; but you should consult a "old-school" plumber in your area.

SOURCE: no hot water
You may need a circulating pump but I can't explain why it was fine before and not now. What I would do is turn the supply off to the water heater along with the power, remove the outlet supply. Open all hot side faucets in the home, using compressed air blow through the pipes if the air comes back at you, then there is a blockage before the hot manifold. If air moves, shut one faucet off at a time to try and determine where the culprit is. I don't know what else to tell you other than that. If air moves through the faucet every time, then you may want to put a circulating pump on. The only other expination is that when they repaired the pipe, some debris or eccess solder is blocking the hot supply. I have seen rocks in units as well. Because of the fix, you may want to take apart each faucet in the house and using a flashlight, look in the hot supply side to see if you can find any debris in those as well. Its not unusual after a repair, to have debris caught in them. Hopefull this helps.

Usually when you are having a problem at only one fixture, and not any others it is a sign that you have a faulty fixture. Hope this helps.

SOURCE: no hot water in sink and shower
it sounds like 1(or more) of the motorised valves arent working.find the valve and make sure you are getting power to it via a tester,if so then it probably needs the head on the motorised valve changed
