Waste hose problem for washing machine

[CHRISX]

Replace the white boss arrangement with a tee and a standpipe. You might be able to fix the standpipe to the breeze block.

Hello Julie Street,

Did You read what I wrote about NOT installing a trapped Standpipe as you described ?

That was the `Expert Opinion` of a Professional Plumber.

I should have explained why not - here is the reason:

It is quite feasible that one or both of the waste pipes that are connected together could be discharging just as the Washing Machine is pumping out.

Although what You described would mean that the tee for the Standpipe would be very close to the Soil pipe boss there is a possibility that a `full bore` flow of water from the other 2 waste pipes could restrict the water flow from the Standpipe / Washing Machine coming into the vertical waste pipe causing it to build up within the Standpipe.

For the few seconds that the vertical existing waste pipe is full of water [imagine a full Kitchen Sink and perhaps a Basin emptying / water running] it is possible that the Washing Machine waste water could pump over the top of the Standpipe.

Even pumping over for just a few seconds this could be a significant amount of water overflowing the Standpipe.

Other Members might disagree with this but there are reasons why Professional Plumbers upsize Waste pipes or connect additional Waste pipes directly to a Soil stack / Soil pipe and this circumstance is one of those reasons.

CHRISX, you may be surprised that an open forum allows all to have a voice and the original poster can take or leave opinions as they see fit.
I think you owe Julie an apology for the tone of the first two paragraphs in your post above.

Agreed, Chris X. I wouldn't personally want to fit a washing machine trap to a shared 1.5" pipe. I have done it on a 2" pipe though. As I said to the OP, at your risk.

Hello rpm,

I notice that as has happened before you are deliberately responding to one of my messages in order to disagree with something that I wrote although there were no incorrect details in the message.

I would suggest that you wait until I write something that is patently technically incorrect - if this does happen I will be grateful for your correction.

As a Professional Plumber I will try and ensure that incorrect `advice` on here is countered by an explanation / the correct details about whatever is being asked about by an OP.

Of course OP`s can decide what course of action / advice to take - BUT it is important for us Professional Plumbers to identify ourselves as such and to contradict incorrect `advice` / details so that they can choose one of the correct methods of resolving their problem.

I meant no insult to Julie Street - I asked whether She had read my previous message and I stated that I should have explained previously why I would not connect a Washing Machine Standpipe to the existing vertical Waste pipe which combines 2 waste discharges.

I then went on to explain the reason for that.

Perhaps You will find something technically incorrect that I write in future that will merit your comments.

I simply thought the words and tone (by using your trademark) was rude to the lady. Nothing to do with being factual or technically incorrect you clown.

Hello again rpm,

Do You think that insulting me in your reply is appropriate behaviour for a `Senior Member` such as yourself ?

It is obvious from this and some of your previous comments in messages to me that you have taken a dislike to me for some reason.

It would be better for the Forum if you did not try to find `reasons` which are not Plumbing or Heating related to respond to my messages.

I don`t know what You mean by `your trademark` - unless you mean that I usually write quite a lot of detail and also highlight paragraphs to explain exactly what I mean in my messages.

I do that to try and ensure that there are no misunderstandings regarding the details that I give.

Although I know that some people probably do not like my long messages I intend to continue trying to make sure that people don`t misunderstand anything about something that I write.

Hello again Julie Street,

Further to my previous reply to You:

As You might have seen a Member has suggested that I was rude to you in my previous message.

It was definitely not my intention to do so.

Please accept my Apology if You did feel that I was rude or too abrupt ?

Could You please let me know if you did feel that my message / the tone of what I wrote did seem rude ?

I would really appreciate a reply.

Chris

C'Mon Chris as a grown man being called a clown cannot possibly be considered an insult unless you have a very thin skin however the term senior could be considered as being ageist.
Further more to acknowledge that your trademark essays and typeface may not be enjoyed by some and then to state that you will continue to post in such a fashion regardless is like sticking 2 fingers up.

 

[Julie Street]

No offence taken. In my experience my method would not cause a problem as the standpipe outlet is already so close to the soilpipe boss and I would not expect the standpipe itself to ever be full of water and it's trap is below the other 2 outlets. Plus unlikely that a full sink and a full basin both discharging at the same time! But I do take your point, and my method, although expedient probably contravenes the regs if I could be bothered to look it up. Just thought it would be easier for a DIYer to do. If I was doing it then it would be a new soilpipe boss but I felt the OP needed something a bit simpler for DIY. Cheers and Happy Sunday!

But I do take your point, and my method, although expedient probably contravenes the regs if I could be bothered to look it up.!

I suspect you'd find that the Approved Document doesn't say anything about it specifically, but I can't be bothered to look it up either. Anyway, UK Approved Documents are not prescriptive, so I don't think the regulations are something I would be especially worried about in this instance, and I do see your point.

As I once said to a friend and customer who once wanted a new standpipe for a dishwasher to sit next to her washing machine, they do, after all, make 2 into one jobbies to allow appliances to share a standpipe (and had the existing plumbing been good, I would have allowed that in her kitchen on the understanding that it might not work if both machines were used at the same time). BUT, as her existing plumbing was poor, I did a new 2" branch for the appliances.

Sometimes it is about what is practicable in the circumstances and on the available budget.
