Plumbing Problems
Having a bit of a mare working out how to change pipework to fit my new drum filter. All could be okay if I use a 4" rubber connector elbow to slightly change the angle of the pipe before the ball valve. Is this a "never, ever do this" type thing or a "not great but will probably be okay" scenario? The alternative involves a lot more work.
Thanks in advance.

Why can you not use the rubber boot after the ball valve.. that would be a much better option

Hi Mike,
Difficult to explain but basically the 4" pipe from bottom drain comes up at a slight angle (solvent weld set too quickly) which was fine for the multibay as it was quite close to the pipe but the drum will be about 2m away and therefore the longer pipe exaggerates the angle and ends up about 20cm off. With a rubber boot I can correct the angle slightly.
No space for the ball valve before the bend. Do the rubber boots ever completely fail? Was thinking of using gold label and then wrapping it.

Hi Letimgo
I agree with Mike, the problem with putting the rubber connector before the valve is that they can deteriorate and you would have no way of being able to close off the water from the BD without emptying the pond to the connector level.
My valve is before the rubber connector on my set up for that reason.
So it’s not a complete no go but I wouldn’t recommend it....
Cheers

Hard to picture quite what you are up against, but could you not use a heat gun to put a slight bend in the new longer pipe to bring it in line with where you need to be?
Others may well disagree, but I wouldn't have any qualms using a rubber fitting anywhere where it is accessible to keep an eye on over time though this is assuming it isn't being placed under stress during operation i.e when opening / closing a valve.

Cross posted but Adyprice makes a good point re future maintenance.

I don’t disagree about rubber fittings, they are great but I would want to have a value before any rubber so it’s possible to change it out without having to drain or plug the pond.

Looks like predictive text strikes again Mike
You've written 'value' not 'valve' unless I'm seeing things?

Bending 4"/110mm pipe by a small amount is relatively easy.
I tried various ways over the years, but the one that worked best for me is as follows:
1. In thick felt tip, draw a line all the way around the point where you want to bend.
2. Put two lines across this line at about 1" apart. The idea is that this small section is not going to get any direct heat and will act as the "hinge".
3. Get a bucket of cold water ready.
4. With a heat gun (have used a blow torch, but must avoid too much scorching) heat carefully around the rest of the line, going backwards and forwards. All but the 1" section.
If the pipe is pressure pipe and thick walled it will take a while to get it supple.
5. When it is hot enough you should notice the pipe begin to flex slightly as you handle it. It must get nice and soft or it will split.
6. The way I do it is to lie the pipe down with the unheated 1" section on the bottom and lift gently. The pipe should bulge slightly on the top. Don't try and bend it too far.
7. As soon as it is bent enough, or as far as you dare, pour on the cold water from the bucket to set it in place.
8. The good news: This method makes virtually no difference to cross sectional area and should not hinder flow. If it hasn't bent enough, make another bend a little further on. You can try it on a loose bit of pipe and only fix it in place when right.
Here is an example of some 110mm sewer pipe I bent using this method. Thinner wall so less heat needed, but same principle:

Just need to double check the jubilee clips ever so often on the flexi rubber boots so The Legend told me

Heard both options too about twisting or not twisting the pipe so that's why I try to use flexi rubber boots where possible.

You can actually buy an adjustable push fit drainage fitting that rotates to your desired angle .Google Toolstation 110mm adjustable bend
