Kitchen pvc downdraft vent pipe fills with water.

I have a kitchen downdraft vent system that slowly fills with water. I have to drain it twice a year with a small pump. The pipe is in sound condition and not broken inside. I think that it was not glued properly throughout the 8 foot in slab run to the outside. The outdoor vent cover has been replaced and caulked around the pipe and cement patio. The vent comes out of the ground outside from under a concrete slab. I would like to know if there is any resolution to this problem other than excavating the slab and kitchen.

I have three 90s on my downdraft unit - 90 down from unit into slab, 90 out from slab to outside, then 90 down again. If you are talking a 6" or 8" dia vent it should not make a difference at all.

Richard, you should be ok, you may want to check it periodically to make sure that grease isn't building up in the low spot... You are adding a couple of bends, but it should still draw well.

SOURCE: Ground rod placement

If this is a Sub pannel that is fed from a main pannel then you don't need a ground rod for it, but you do need to run a ground wire in the cable that feeds it. So if it is fed by a 220 volt breaker in the main pannel it needs both hot wires, a neutral, and a ground wire in the cable.
Also when you get to the pannel do not attach the ground bonding jumper to the neutral bus in the sub pannel. each of the 4 wires will be seperated at the sub pannel.
Presto.

What is the minimum vertical vent distant from top of water heater to top of cap. Water heater is stand alone outside furnishing water for military force provider showers unit.


Generally 40 feet for ordinary atmospheric-vented household water heater...
Straight run to roof.
Atmospheric means no power vent... just hot air drafting upwards
Google search: gas vent height code

Atmospheric venting code depends on 4 basic factors:
Diameter of vent--- bigger vent, more draft
How many water heaters are connected to same vent
BTU per hour rating of water heater-- the more gas that is burned per hour, the bigger the vent needs to be
How straight the pipe is -- are there any horizontal or lateral runs

http://waterheatertimer.org/pdf/Bosch_Checking_the_draft.pdf
http://waterheatertimer.org/pdf/checking-the-draft2.pdf

Other factors can include
-wind conditions... higher wind across top of vent pipe on roof can reduce draft, and cause downdraft that blows deadly CO into same room as water heater
-vent termination near high walls, trees, high roof peak etc will reduce draft or cause downdraft
-amount of incoming air supply... if water heater is inside a closed room, then there is no air to draft up the pipe, burner will shut down or burn lazy yellow instead of clear blue
-stuff piled up around water heater that obstructs air intake
-dirty air intake screen that reduces air intake
-vent fans inside same room as water heater that pull air down the vent and cause reduction in water heater draft
-generally elbows reduce draft by 10%
-vent cannot terminate near any window door or air intake for another gas appliance
-bird build nest on top of vent pipe after vent termination falls off
-highly acidic gas by-product causes large amount of condensation inside pipe that burns hole in pipe or drips down and damages combustion parts...blower and inline condensate trap and drain might be required
-multiple water heaters installed on same vent line.

Have 75 gallon gas water heater. Can I run 90 PVC off top power vent without vertical PVC first? Have Richmond unit.


1) I believe you can immediately elbow the PVC pipe.
There is a limit for how many elbows can be used between blower and termination, and limit is determined by diameter of PVC pipe.

2) Copy following link for venting resources and typical Rheem and Richmond power vent manuals, and diameter-elbow pdf from Bradford White.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#venting

3) Richmond is Rheem. Product manual will show specifications for venting.
Product warranty is voided if installation does not follow specifications shown in manual.

Drain inside house from a c is over flowing.central air



I am a certified HVAC Technician. I have worked in the field since 1996. I have seen this hundreds of times, if not a thousand times, in the past. Every central air conditioning and heat pump system comes with TWO drain pans, The MAIN drain pan is located within the AIR HANDLER (blower) UNIT, while the EMERGENCY DRAIN PAN is extremely LARGE and sits under the ENTIRE AIR HANDLER (blower) UNIT. The ONLY time water will be INSIDE an EMERGENCY DRAIN PAN is when the MAIN DRAIN PAN condensate drain line is CLOGGED, causing the MAIN DRAIN PAN to overflow. What causes the drains pans OR the drain lines to become clogged is slime and scale from the condensate water as well as debris from within the attic that may have either been blown by the air or may have simply have fallen into the emergency drain pan; or some insects from the out of doors have traveled up into the PVC Drain line and built a nest on the downward side of the P-trap. The P-trap is designed to prevent critters from entering your home through the PVC drain lines. Most CLOGS occur at the P-TRAP location.

The BEST thing to do is:


1. Locate the WHITE PVC drain pipe outside your house and ensure there is NO water draining from it.

2. Locate the same WHITE PVC drain pipe inside your house. You should notice a "TEE" where two WHITE PVC drain pipes merge into ONE WHITE PVC drain pipe.


Follow the below steps, in the order shown:


A. FIRST, find another person to act as your second set of eyes at the end of the WHITE PVC Drain Line that is located outside of your home. That person will be looking for water or debris to EXIT the end of that WHITE PVC DRAIN LINE.


B. SECONDLY, locate the WHITE PVC "P-TRAP" inside your house. It is normally located within a couple to three feet of your indoor air handing (blower) unit.

C. THIRDLY, very gently lift the entire WHITE PVC drain line up in the air as high as you can without breaking it, and slam it down onto the rafters or attic floor or garage floor. You are attempting to dislodge the CLOG within the drain pipe WITHOUT having to actually CUT the PVC and without damaging or breaking the WHITE PVC. Depending on how old the system is, it may or may not be brittle; and it may not take much to damage or break the PVC, which will cause leaks. So, be very careful at this point.


D. Ask the person outside if anything has started to EXIT. You can ALSO usually hear water start to drain if you put your ear up to the drain line. If the person said "NO"and if you don't see the water level getting LOWER in the EMERGENCY drain pan, then REPEAT step "C" above.

E. If the person informs you that there IS water now starting to exit the WHITE PVC DRAIN PIPE, you should then wait until all water has drained from the EMERGENCY DRAIN PAN; and then pour at least 1 quart of BLEACH down that drain, from the EMERGENCY DRAIN PAN exit. The BLEACH will further clear out any SLIME which may be remaining within the "P-TRAP" and will also CLEAN OUT and DISINFECT that drain line.

If the above steps do NOT work for you, then prepare to go into the next LOGICAL phase of your attack. Please NOTE: I am limited to 10,000 characters in my response, so I'll repost additional STEPS in another RESPONSE. Good Luck!!!

I would like to put my cook top on an island in the centre of my kitchen how would i vent down thru a crawl space???


Get a downdraft cook top and drill a hole. Then run the piping to the outside wall of the house and drill again and run the piping thru to the outside. They make outside wall vents like dryer vents only bigger to accommodate the bigger vent pipe. Happy crawling. It will look and work great if you get a good stove. Do your research.

You can't stop condensation or humidity in the house, especially in the bathrooms. A few choices: replace the hinges, or oil the hinges with WD-40. Install a vent fan (even though you have a window) and replace the pipes with PVC pipes. Metal drain pipes will always rust, because they drain water. Replace all under sink drain pipes with PVC

Check your waste pipe roof vent.

If it is not free (of dead animals leaves etc) - it creates a suction - rather than a drain in your pipe.

Downdraft exhaust not working properly


I pumped out water that somehow collected in the exterior exhaust pipe. Even though there is a hood on the outdoor pvc pipe, it still filled with water; not sure how but after extracting the water, the fan works great now.

Install a Thermador UCV36 cook'n'vent


Hi schmidt_rich,

I'm Harvey the Master Plumber.

Your question is: You took over as owner builder when your builder "took the $ and ran". You are installing kitchen cabs now and discovered the PVC vent pipe (which goes into the foundation and out the side of the house) is in the wrong place for the location of the downdraft unit and integral blower. The vent is actually under the electrical connection panel. You were told initially( 2 yrs ago when you bought the downdraft cook'n'vent) there could be no bends in the exhaust fan route or it would change the effectiveness. Does anyone know if it is ok to put a bend in the connection to the vent? Or do you need to redo your kitchen cabinets?

I can syphathise. I have had to deal with this same problem. I have found that one ell will not degrade the effectiveness enough to notice. If you need more then you may need to adjust cabinets.

Feel free contact me again!
