If you are talking about the drain line, usually white plastic, this could be because those lines get clogged all the time. The best way to fix that is to **** it out with a wet/dry vac. You can also cut the line apart and see if the fitting threaded into the drain pan is cracked and replace the piping all for probably under 5 dollars. Another thing that could have happened is that the pan itself is cracked where the piping is screwed into it. For that, the easiset thing to try is to seal it up with caulk and let it dry before turning back on. Let me know what you find out

Why does the central heating lose pressure all the time?

hi Marcella.
The cause of the boiler losing pressure can be due to wear and tear or an underlying fault on either the boiler or the central heatingsystem. In most cases, we find that the central heating has been checked for air in the radiators or work for example a radiator has been taken of the wall.

Why Is My Boiler Losing Pressure Q&A - Emergency Plumber

What would cause a boiler to lose pressure?The following are the two most common causes of lost pressure and how to spot them. If your central heating is losing water pressure that usually means it is losingwater. This could be due to a leak somewhere in the system, which is not only bad for your water pressure, in could end up causing damage to your home.9 Jun 2015Why Your Boiler is Losing Pressure ' DHS Heating and Plumbing, Bristol for: What would cause a boiler to lose pressure?

Got a trauma ultrastore water heater in my bailey senator caravan water is coming out from either overflow/pressure value or maybe a leak can anyone advise on how to try and sort this out

There is no overflow pipe on the water heater. There is an overflow/vent pipe on the fresh water storage tank though. It is normal for this to leak water at times.

Its possible you might have some type of winterizing hot water tank drain. But that should have a valve on it. If you have such a valve it should be shut off and not leaking.

That said we move on to the water heater. This is assuming you have a water heater leak. Or a leak with something connected right at the water heater.

You could expand this concept to move on to other pressured parts of your plumbing system to troubleshoot and isolate.

I would remove the pressure relief valve and rig up a fitting you can screw in. Set up with a pressure gauge and a air filler fitting like is on an inter-tube/tire. Some plumbing stores sell them already made up.

You might have to custom adapt this using some rubber hose rated for air compressors. Using barbed to threaded fittings and hose clamps to withstand pressure.

Install your air valve/gauge in place of the relief valve. If you have bypass valves this is a little easier. Close off the bypass valves to isolate the tank from the plumbing system.

If your plumbing set up has no bypass valves, disconnect the inlet and outlet plumbing lines. Screw in appropriate sized plugs in the two tank holes. Use teflon tape and make sure they are secured. (All easier said than done).

With an air compressor or tire pump pressurize the tank to 50psi. Soap all fittings, and your plugs, to insure you have no leaks around anything screwed in. Let this sit overnight. If your pressure drops off you have a leak. If your pressure holds I would suspect the relief valve that you removed.

You could move your air valve/gauge set up to the water inlet or outlet pipe and reinstall the relief valve, to test the relief valve. Pressure up to 50psi and soap everything again. Let it set overnight again.

If you suspect the relief valve before any of this troubleshooting starts, you might just start by installing the air valve/gauge in the inlet or outlet right from the get go.

Tanks often get pin holes on the bottom as they start to corrode through. Hard to visually find in many cases. Pressurizing with air will tell you whether you have a leak for sure. Not get everything wet in the process. Using common sense and a process of elimination, you should find the problem. There are also drain valves and in some cases anode rods that are screwed into the tank and may be a source of the leak? Soap all of these while troubleshooting.

The image is my setup. It is a little more fancy than described. I have a little valve off a T so I can use the little turn wheel and open the valve to relieve pressure without unscrewing everything. That also beats holding in the little spring loaded needle valve of the "tire filler" valve shown sticking out the right side. But I think you will get the idea of the basic concept?

Central air conditioner

first you will have to find out where the leak is. a lot of times it can leak where the high and low pressure lines connect to the back of the compressor. the rubber o-rings often fail. replace the o-rings if that is where your leak is. and always grease the o-rings when installing the new ones.

My radiator has a leak on the top how can I fix it without having to replace it just yet

does it leak from air vent if so you can unscrew return valve cover and close it of with adjustable spanner, turn the flow to off. using a vent key remove vent screw, should not be too much water but have mop bucket and old cloths at the ready.wrap some PTFE tape (got in most diy shops) around vent in anti clockwise direction and screw it back in open valves and bleed rad to vent the air... alternatively there is some good plumbing videos on you tube covering a lot of plumbing problems..

My kenmore window unit AC started blowing a white smoke like substance. It seems to be cooling fine. What is this and is it a concern?

The two things it could be, #1 - evaporator leaking refrigerant - unlikely if unit is still cooling o.k. because window units do not hold a lot of refrigerant and if there is a leak bad enough to blow smoke it would have stopped cooling by now. #2 - the humidity is high and the unit has cooled the air right at the discharge down below the dewpoint, a common occurence in window units and automobiles due to the short duct distance from the evaporator to the air outlet whereas with central air systems having longer duct systems the air gains more heat before being discharged into the room.

I need to find a leak in my Carrier Air Central Air cond. I'm thinking it may be the A-coil as it keeps freezing up. Can I use compressed air and soap/water spray around the A-coil to check for leaks?

You cannot use compressed air as it will introduce moisture into the system. You can use dry nitrogen. Prior to searching, look your system over and look for oil.........oil will leak out with the refrigerant and often times you will notice the oil collected in the area near the leak. After pressurizing with dry nitrogen, you can use a soapy mixture to search for the leak. Leaks in the A-coils are commonly found near the tube sheets; however, they could be anywhere in the coil. Good Luck in Your Endeavor!!! :-)

Spa jets are not at full output. I have a new

Thank you for posting your question here on

Air in the system indicated suction leaks so you will not find 'leakage'. Instead you are looking for ways air can get in before or at the pump. That section of the plumbing is under a vacuum and a leak means air gets sucked in. Common areas are the pump seal and the pump strainer cover. Plumbing connections at the pump and then finally skimmers and other plumbing connected to the suction side of the system. Do you have a lot of air in the pump strainer basket area? If so, start with the gasket that seals the lid in that area. Is there any sign of water leaking under the pump? If so, replace the pump seal. If none of these cure your issue you may need a pressure test on the suction side of your plumbing to better identify where the leak is.

HI Dear water from dishwasher is leaking from

there is a cloged line between the air gap and the disposal (if you have one) or the drain under the sink.
you will need to remove the pipe and flush out with water. this is usually a rubber hose. most of the time, the clog is at the disposal where the rubber hose connects.
you should be able to see the clog once you remove the rubber hose. clean this out ( I use popsickle sticks) once cleaned out, reinstall the hose and try your dishwasher.

Nutone central vacuum leaks brown liquid

Dear lord, that is the most absurd thing I've ever heard. Who installed the Vac and DW or were they both in the home before your time?

Normally, if liquid drips out of a CV outlet it's because it was sucked up during vacuuming. However, if your vacuum runs or has suction at the outlets due to the dishwasher running, you have a low voltage gap being bridged by either the dishwasher's wiring or by liquid leaking from it onto the CV wiring somewhere.

Bottom line, you have MAJOR issues inside your home with one or both of the systems, and if there's liquid, there's a dishwasher to be worried about! Look below it for leaks into the basement/lower floor; follow the plumbing (especially the drain waste runs) and figure out where the damage is before your house suffers the lot.
