2 nasty little problems

[Jon W]

Hi Everyone

I wonder if anyone could help me with a couple of problems that I'm trying to solve for someone;

Problem 1
Air pipes - the pipework from 2 bottom drains containing the airlines from the bottom drains has been left below the waterline and have been allowed to set in the concrete so close together that they are touching. This means that there is no possible way to use rubber boots or solvent weld joints to extend the pipework above the waterline (incidently the diameter of the pipework is non-standard). The only workable solution I can think of is to cap off the pipes using massive plugs of mastic/epoxy resin and fabricate caps to accomodate the air pipe.

Problem 2
The bottom drain is a Spindrifter. The stalk for the airdome was fitted into it's socket with a generous amount of mastic. This subsequently had to be removed because the airline was pinched. When it was removed, most of the socket came with it (I was present for this part of the operation - it required a massive amount of force). There is now nothing to mechanically secure the stalk and socket to the bottom drain sump. The only solution I can think of is to create a base of different diameter pipework to provide a greater surface area for contact and use generous amounts of a very stong epoxy to create a bond with the bottom of the drain.

I would be grateful for any input with either of the above. The owner is driving himself and me potty; he's so close to getting the pond finished and yet so far!

Regards

Jon

hi jon ,with problem 1 is it possible to insert a smaller diameter pipe into the existing ones and then solvent weld them , problem 2 , can you grind down what is left of the socket and then solvent weld a flanged tank connector in its place this would give you a new socket, hope it goes well for you.

Hi Gary

Problem 1
Did think of this but unfortunately the air pipe diameter doesn't correspond to anything I have come across before - apparently it's some sort of BT ducting pipe. I did think of creating a sort of slurry from solvent weld glue and plastic shavings to use as a sort of mastic and use the next smallest diameter pipe but didn't want to risk it.

Problem 2
Sounds like a good idea. I will look into it and see if I can find a tank connector that fits the diameter of the cover stalk.

Thanks for your help.

Regards

Jon
