Look at all my stars!! Senior Member 2,547 posts Joined: Sep 2011	Hi all, Wanna ask, for the floor drain of the washing machine, normally how do you finish it? Currently I just ask the contractor to extend the drain pipe a few inches above the floor, like the picture below. So later I can just put the hose into this pipe. But I also come across with this type of floor trap, with an adaptor for the hose. Just wondering, if this type will be a better option? Thanks

You can buy the backflow prevention valve from Taobao. About the one integrated to the flow trap, I think it is a solution for apartments. In China, many property owners converted their balconies into laundry areas. So, the floor traps with adaptors are hot selling products. thanks for the info. actually mine haven't done yet, the picture is from google. now considering which one to do since the contractor is going to do the tiling soon

The direct discharge is without any trap. There is no water seal to prevent the foul smell or vermin ( cockroaches / insect ) to go back to the washing machine. Your washing machine will be exposed to the risk. The option with the floor trap has the water seal inside the floor trap. The water seal can prevent the foul smell & vermin to enter the washing machine. great, that's what i read also about the smell. but with the adaptor, i'm not sure if it will fit the standard hose from the washing machine or not

The air need to enter the bottle so that water can flow out easily. Since you have a fixed PVC inlet, I'd suggest that you use something like Y connector. One for water to go into drain and left the other one opened for air to come in. thanks for the info. actually mine haven't done yet, the picture is from google. for my idea if just using the pipe, the pipe will be slightly bigger and i will just slot in the washing machine hose into the pipe, there will still be gaps around the pipe and hose for the air to go in

If the size cannot fit, look for a connector from the hardware. There should be a connector which can connect properly. ya will check out a bit on this, else different brands will have difference size/type then maybe can't find it locally too

Having problem deciding the plumbing and connector to floor drain at my yard. I need to discharge water from 2 outlets (from sink and washing machine) to 1 floor drain (existing drainage). Layout plan at yard as attached picture. Current plan, to use H-type connector (like the attached picture) with the water seal (self sealing). I prefer to have water seal due to the functionality of blocking the smell and vermin like u mentioned here. The thing is i’m not sure if this plan is the best for the water flow as i have seen a lot of sharing that with the water seal the water from washing machine tends to overflow the floor drain. Also not sure if 2 outlets to 1 floor drain is the best option for the long term use. Someone commented that most probably the grease water from sink will flow to the washing machine Layout plan at yard H-type connector for sink and washing machine outlets the water seal will depends on the downpipe size of the existing drain. if it's a big one like 4" diameter or bigger then it should be ok. if it's smaller then will have a risk of overflowing Bijisss liked this post

With this plan the 2 outlets will be extended directly into the floor drain. Good idea, but make sure the contractor do some waterproofing ya Bijisss liked this post
