Wow, thank you!

[@Plumbing.repairs]

Thank you. I have spent damn near all day trying to research issues on why my sink gurgles whenever the washer drains and this I think answers my question. I am subscribing to you, I just bought a new home and as I haven't found any major issues really, I am noticing some plumbing issues come up. Thanks for the video

[@dereton33]

No problem. Thanks for subbing.

[@monieamara]

Thank you for the practical teaching. I am a architectural designer. I had to place in the ground floor a vent to the utility tub but, I could not place a terminal vent from the tub to go out of the house. This is a perfect alternative.

+nira bottinga . No problem.

[@suto3329]

Thanks for the video - I like your channel. After fitting the anti-syphon trap I still have the same problem though, gurgling and bad smells when using the washing machine - is there anything that can be done? Thanks

[@johnschlesinger2009]

Thanks - good video. I bought one of these, and on opening the cap on the air inlet valve, noticed a round piece of plastic sitting on top of the valve. This needed to come out to allow air to enter the trap.

[@pro6seller]

At the top of the elbow where the vent is. Do you need to remove the blue blank adapter that is under the white cap when you unscrew it? Thanks

[@ianmowbray3284]

great tip as always.

[@joela8437]

Great and very well explained. Only question as the washing machine, dishwasher, boiler condensate or water softener waste goes in after the trap does the smells from the drain effect these appliances? Would it work well to put a trap in under the sink as you have here and then attach the appliance to the waste after and then add another trap?

[@dereton33]

Yes it will but just remember another trap may well block easy.

[@TheDirtytwister]

Very helpful cheers pal

[@dereton33]

No problem.

[@cathyhable]

i think i have the same problem living in a tower block since having my machine plumbed in when the machine is letting the water drain out before the rinse fresh water comes in there is a terrible rotten egg smell i have cleaned the draw and filter and still smells do you think it could be my plumbing??? thank you for your helpful video

[@dereton33]

Yes the machine empties the trap seal when rinsing and empting, this allows bad smells from the waste to enter the kitchen.

[@hardworker2877]

I was wondering can you give me some help. I am building a bathroom in the basement and I don't want to open the floor. my question is. can I cut straight into the toilet stack from the upstairs

[@dereton33]

Yes if you use a Saniflow pumped system.

[@jackiacovou6196]

Hello Dereton33. Thanks for the great vids you post for us amateur DIYers. I have a question. I have a double kitchen sink with 2 p-traps underneath the sink. Another smaller pipe joins one of these p-traps higher up which comes from our dishwasher. Recently we have been getting a lot of gurgling when water drains. The gurgling happens from both taps. So I bought 2 of these anti syphon p-traps from screwfix and I still have a gurgling issue. I know I don't have a blockage further down the pipe as I have put a snake down the whole length of the down drain when I took the p-trap off. Any ideas what the problem might be? When I fitted the p-trap I fitted them without any adjustment. John Shechsinger commented and suggests that they be some kinda plastic that needs removing. ?? Or could it be the vent stack but I thought the anti-syphon p-traps would deal with this. No other sink in my house has a problem. Just the double kitchen sink. And we have no smells coming back at us. Any ideas anyone? Thanks.

[@dereton33]

Those traps normally work fine. If you have room on the pipe you could also try a non return valve.

[@kboo1862]

Interested in your solution. I have the same problem you had. Double sinks. Never had gurgle before. No smell. Now gurgling.

[@TheAmysarah]

I have gurgling noises coming from my wash basin tho it is draining, the basin is located next to my washer and dryer. I did clean some of my painting supplies, and after I did the gurgling sounds started. Is there anything I can do to solve this problem or should I call a plumber?

[@dereton33]

The drain is partially blocked causing a sucking gurgling noise from your sink. Try a plunger first.

[@tarangamble9265]

my washing machine will not drain and is backing up into the sink, now the water collecting in the sink won't drain or moving very slow at this point. we have used a snake with no luck also cleaned the drain pipe under the sink. do you have any suggestions?

[@dereton33]

Yes, get a cheap pressure gun about £11.00, if you have a look on my channel there is a video showing how to use one and with links to buy one.

[@Spongesyellow]

If the washing machine fitting is placed directly into the mains, the smell that comes into your washing machine is really bad.

[@kdmq]

There might be a trap for the wash machine hidden from view I can't tell.

[@jaybrickman1094]

Probably have an S trap..the pipe in between the trap weir and sanitary tee has to be at least 4 inches

[@martinblackmore4515]

I have had a bathroom and the traps are very shallow and I cant see how they hold water and keep the smells at bay. They are shallow to fit draw dividers in the draw. They look like they are concertinaed. Have you come across these and do they work.

[@dereton33]

Yes but they do still work, they can dry out over time if not used though letting drain smells back in.

[@chrisread2265]

hi my washing machine wast still comes up in the kichen sink or do have to call the council out to have a look please let me now chris from norwich uk

[@dereton33]

The sink waste is blocked.

[@niksrathore6280]

A pen nib(less than an inch) fall into my wash basin's pipe ...and after washing hands there are soap bubbles around the pipe at the bottom.... I didn't notice if it was before..I just wanted to ask ..is this because of that nib??

[@dereton33]

No I would not think so niks.

[@jamiecoldrick7301]

do you not get a smelly washer as its connected to the soil side of the water trap ?

No.

I cleaned my pipe out yesterday but still get the gurgling noise no water comes up into the actual sink which is good

[@maxziemer3631]

[@bambikiller6993]

Show the part where you undo the trap and all the waste spins around.please and you have to seal the waste again..

[@jennypinchbeck7688]

My washing machine smells wen filling with water wen first turnt on ,it's connected to drain pipes under sink ,any suggestions on what it can be or can do plse

[@dereton33]

Make sure your drainage pipes are not blocked at all. Give the machine a flush through type rinse to clear any stagnant water.

[@elothmanilavandou3087]

Hi there and thank you for your helpful video !!I do get the gurgling and the water coming up then it goes back down again 😂also the smell .I don’t have the washing in my kitchen it’s in the corridor So I’m really puzzled to where it’s coming from any help is very appreciated 👍

[@dereton33]

Try changing the trap as in the video.

[@elothmanilavandou3087]

dereton33 ehhhhhh ? But it’s not the same

[@TheAdventuresOfJimiJaden]

I remember there were always be sewer leaks causing the toilet to clog and our sink to start bubbling. It would make our house smell like shit. We had to call a plumber.

[@dereton33]

Smelly job

[@jackiacovou6196]

Hi, I have a gurgling kitchen sink. I have added one of these anti syphon p traps and I still have the gurgling - I don't think that you can adjust these in any way - I just replaced like for like. Any ideas?. I have a double sink unit and the one that gurgles also has the dishwasher draining into it. I only changed the P=trap on the one that gurgles. Is there a problem further down the line? The sink seems to be draining ok. There are no smells just a gurgling noise. And all other taps around the house work fine with no gurgling.

[@dereton33]

You may have a partial blockage down the pipeline that is causing a sucking. Give the waste a blast with a cheap pressure gun.

[@jackiacovou6196]

@@dereton33 Thank you. Thats what it was. The other side of the wall from the kitchen sink we have an outside tap with a straight drop drain. somewhere it connects to the kitchen drain. Putting a snake through there unblocked the drain. There were some rock hard fat deposits. Gurgluling has stopped. Looked into pressure guns and think I will get me one of those for future use.

[@conhawks]

i fitted one of these anti syphons and it doesn't do the job. best

[@mackenzierobinson11]

I live in a manufactured mobile home and my master bathroom has a horrible sewer like smell that comes and goes randomly under the sink but smells the whole bathroom up. I’ve noticed i can smell it a little when I wash clothes as well since the laundry room is beside my bathroom ( other side of the wall) we have had pipes checked and all clear. Do I need to seek professionals? Can you give any insight ?? It would greatly be appreciated.

[@dereton33]

The traps are being emptied by the washing machine.

[@mackenzierobinson11]

dereton33 can you explain a little more on what that means?

[@chriswyman]

I have this installed but when I reconnect everything the sink drains v slowly even though there is no blockage. How should the vent cap be tightened and do you remove the blue plastic stopper inside?

[@dereton33]

Remove the stopper.

[@chriswyman]

@@dereton33 that still doesn’t seem to have resolved the issue

[@mandycheatle2672]

Hi, I replaced my kitchen P trap with one of these anti syphon ones. Exact same pipe work as video apart from I have an appliance nozzle for washing machine. No leaks at joint but when I empty a large bowl of water down the sink, the valve part leaks….does this mean it’s faulty?

[@dereton33]

Yes they should not leak.

[@mandycheatle2672]

Thank you, I’ll take it up with the supplier

[@mandycheatle2672]

Would it matter how big the distance is between the bend with the anti syphon on it and the bend taking the water out? Just noticed mine is slightly smaller than the one in your video. There’s only around 1 inch of pipe you can see between then 2 bends.

[@peterrabbit8181]

I have the same problem but without using a wash machine...What do I do????

[@dereton33]

Best solution is to change the trap for an anti syphon one.

[@thesoames2012]

i have this problem is there any other way resolving this i cant afford that method..maybe chemically?

[@dereton33]

Replace the trap with an anti syphonic one.

[@thesoames2012]

thankyou good sir

[@mikehor100]

dereton33 i live in an apartment my neighbors have an electric toilet and the drain from our sink is connected to the pipe that runs from their apartment, when they flush the toilet the pressure pushes up the water in our u bend and it stinks! is it possible to have a tap underneath our sink so we can close it when not in use? Thanks

[@shaunsmith8386]

a really bad design those sink washer traps ,when I use the washer after a few days the smell that comes out the plug hole in the sink is horrendous !

[@dereton33]

Yes it is a problem.

[@JohnDoe-xl1qs]

The bad smell was probably the dead mouse

[@dereton33]

Squeek.

[@lesflynn2392]

Install the "p" trap on disposal side

[@dereton33]

Wont make any difference.

[@80sbreaker]

Hi I live in Tijuana Mexico most places apt and hotel don't have that p trap because previous renters will always steal them when they leave to resell them , what can I do or use to stop those fumes when their is no p trap

[@dereton33]

Use a non return valve.

[@daniellemccarter5706]

It’s driving me crazy the gurgling can’t watch a f movie quietly.
