SOURCE: The pressure release valve keeps

If this is a water heater, replace the valve. You can get them at Home Depot. If it is an air conditioner, don't worry about it. The water is supposed to run out.

SOURCE: Combi Boiler - Hot water pressure low

I have a 1 bed flat, above an old pub. I have a combi boiler but my water pressure is ridiculous. The shower water runns down the shower head. I'v been told that the cold water feed to the building is split to two boilers, one to the pub and one to me. Im thinking of installing a shower pump in between the boiler and the shower. will this work as my friend says he has done this and it sorted his problem out. I'v looked it up on the net and everything says this does not work. Help please.....

SOURCE: No cold water

Anti Scald Valves have an adjustment under the handle (remove handle) to allow so much hot water in no matter how far handle is turned. Its possible that the adjustment is set to allow only hot water in, this of course defeats the purpose of anti-scalding. Check to see if you can adjust this back. Good Luck have a Great Day. Please give a 4 THUMBS UP if this free answer was of any help.

Setting our machine on warm , but the water s hot , both hot & cold taps are fully turned on .


Check your hot/cold inlet valve and solenoid. It sounds like your cold water side of the valve is stuck shut. The valve is found by following the inlet hose right to it. Also, do you have a domestic well as water supply? Sometimes fine sand from a domestic well will plug the valve screen. It is also possible that other mineral would plug the screen. These things would happen gradually, though, not all at once.

Valve Pressure Reducing or Pressure Reducing Valve


dfef4ee.jpgThe pressure reducing valve on a boiler is the way that the water pressure in the boiler is controlled. The standard pressure for many hot water boilers is considered to be 12 PSI. To keep the boiler pressure at or near the 12 PSI mark a small valve is used for pressure reducing. Most domestic water systems run between 20 and 60 PSI, so the pressure must be reduced for the boiler.

This pressure reducing valve is installed in the pipe that goes from the domestic cold water to somewhere in the piping on the heating system, usually at or near the expansion tank. The valve is mostly maintenance free but will create some problems at times. Some of the things that can go wrong are:

  1. The valve seat can get dirt stuck under it causing water to leak by and increase the pressure in the boiler, causing the relief valve to release water periodically.
  2. The valve can become plugged with dirt causing the boiler to not have enough water pressure, which will cause circulation problems with the boiler pumps.
  3. The valve can leak causing a mess around the boiler area.

Replacement of the pressure reducing valve is not difficult if the installer strategically placed manual valves so that the reducing valve can be isolated from the rest of the system for replacement.
If the water pressure reducing valve fails in any way, it is usually best to just replace the whole valve rather than trying to repair or fix it. I have tried a number of times with only temporary results. These valves are not a high dollar item and the time it takes to fix them is not worth it.

My boler will heat the hot water & heating but not the hot water on its own


This is possibly because you have a zone valve that has stopped working, motor maybe burnt out or could be that it is permanently open . Some valves have a manual control that clicks into position, these valves are usually placed adjacent to your hot water cylinder
Hope this helps

My pressure relief valve keeps blowing more so when it is hot any ideas please


Pressure relief valves open on high temperature as well as high pressure. They do go bad and are replaceable.

Consider calling the plumber. It is not very expensive part and the plumber can change it quickly.

If you just want to do it yourself:
  1. Write down the make and model of the water heater.
  2. Go to a real plumbing store and buy a new one.
  3. Turn off the heat source (the gas or electricity)
  4. Turn off the water inlet and open a hot water valve at any sink to take the pressure off the heater.
  5. Remove the old relief valve. It may take a long handled wrench.
  6. Install the new pressure relief.
  7. Close the sink valve.
  8. Turn on the water and check for leaks.
  9. Turn on the heat source.

Good luck.

Saunier Duval ISOFAST F35E on hot water only makes a noise like a motor bike that vibrates through the pipework, this does not happen when the central heating is on, any ideas as to the cause.


The water pipes (steel) are probably full of rust. The noise is air in the pipes.
Use the pressure relief valve to let air escape.
The risk is if the relief valve is old it may not shut off.
Also air will build up again

Domestic hot water works but no hot water to baseboard heat


If its a one story house, the system pressure should be somewhere around 10 to 12 psi. There should be a PRV (pressure reducing valve) on the domestic water line supplying make up water to the boiler. The shut off valve in that line should be in the open position unless the prv leaks through and slowly overpressurizes your system to the point of tripping the pop-off valve. If so, then the manual shut off should be kept closed then opened only to boost the pressure up a bit in the system. It kinda sounds like you are suffering from low system pressure.

If there is a vent or vents in the system, try bleeding them into a coffee cup and you may find it sputtering air/water mixture. Bleed them until you have full water flow and make sure you keep approximately 10 psi in the system.

Wickes 102 combi boiler constantly loosing water pressure


It sounds like your thermostat could be the problem. Have you noticed the boiler cutting off at all, or does it run continuously until it goes out on low water?

You stated, "when boiler is on", so I am wondering how you get the boiler on. If your boiler is controlled by a thermostat, you need to check it for a cold draft possibly from behind the thermostat in the wall where the wires come through. The thermostat should never be on an outside wall. The thermostat could be defective.

An aquastat can also control your boiler. If you have an aquastat, check the setting, typically 175 - 180 degrees. You should also have a "high limit" which should be set at 210 - 220. Some people run that high side limit higher; not a good idea - defeats the purpose. If the aquastat is set too high, the boiler will operate too hot and the problem you have will occur.

"pressure rises and pressure relief valve opens" This could mean that your pressure switch is prematurely venting. Check boiler temperature to see exactly at what temperature the T&P valve purges. If it blows off below the high side setting, either adjust or replace. The T&P valves are usually not adjustable. That blow off temperature is stamped on the head of the valve. So, if it discharges too soon, replace it.

Have you actually seen evidence thgat the T&P valve is opening? You may have a bad bladder in your expansion tank and your system may have air in it. Your boiler should have 12 psi when cold and 20 - 22 psi when operating. Check your boiler pressure guage.

"
this eventually drops below the minimum operating pressure" Technically, there is set point for a NO MINIMUM OPERATING PRESSURE. That is a function of the amount of water in the boiler. If the T&P is blowing off, it will vent water from the boiler and the boiler pressure will go down. There is a minimum operating TEMPERATURE.

Your boiler could be low on water. You will have to manually fill the boiler. Be careful of thermal shock to the boiler. Feel the piping, and fill only when the circulator is running. Make sure the water is not going directly into the boiler. The supply water should go into the circulating supply side which feeds the radiators, radiant floor, or base board circuits.

All this will adversely affect your hot water. The heat exchanger for the potable hot water may have scale build up in it. Using the hot water keeps the boiler running, and a scaled heat exchanger will give you cooler hot water and the boiler keeps running. If this is a problem, you will need to replace the heat exchanger. A better idea is to not use the boiler for your domestic hot water. Why run the boiler in the summer?

Tp valve opening and dumping water


Certain water heaters can only handle so much pressure from the main line. There is a pressure controller between your water meter and you house, it's called a pressure regulator. You need to call a plumber to check and see if it needs to be adjusted or even replaced.

Changed cold valve


What brand and model do you have, most domestic units have a combination hot/cold valve? You just need a meter too verify the valve is closing, if the valve solenoid is closing you may be having a water pressure issue, too much water pressure can cause leaks.
