Hey guys
I had someone come over to try restore my pond

It is around 3.5 metres x 5 metres
Lovely water fall drop over some slate

Man suggested putting a pond liner over the pond concrete said that liner would be £300-£500

then basically said to fix everything
It would be 2-2k

that would include fixing all of the water fall with mortar cement basically rebuilding the fall with the slate etc

Felt that was a steep quote
And thought about doing the job myself now

any tips or hints on the project?
Also which pond liner n paint would work?
 
I have only ever built a few ponds so I am not an expert. The main thing is to get liner under everything so even if waterfalls and so on leak, it doesn't matter because ultimately the liner stops it escaping in to the ground. So you put the liner in the main pond area then lay another sheet under any waterfalls or whatever, running in to the main poind so any water coming from your filter or waterfall or pumps all drains in to the pond. Then you don't need to seal stones or use waterproof mortar.
Liners come in a variety of prices roughly according to how long it will last in sunlight. In ye olden days they would just use clay which of course lasts forever. Liners come in a variety of prices roughly according to how long it will last in sunlight. Personally I don't think it is necessary to get the absolute best. I have had ponds last far longer than their liner lifetime suggests.
There are special paints to seal concrete, but I have never used any of those so I can't comment.

so out of interest which pond liner would you all reccomend?

When I last did a pond I think I got a liner that lasted 10 years, not the best but I thought it was long enough, but the pond is still going fine some 20 years later. Thing is that as long as you keep any liner out of the sun then it will last forever.

ok thanks

so one of my pipes is 55cm internal diameter - how can I get a pond hose size for this? I think I will need some type of reducer from 55cm to 50cm then attach a 50cm hose
but what part could that be?
 
With paint on concrete you’d need to ensure the concrete will never crack. It’s possible but think rebar and concrete lay to prevent any ground movement from causing the pond to leak.

A liner should have underlay and you want to check there’s no stones or sharp edges.

I have a liner based pond atm. You need to get the rubber rather than plastic liner. It’s not difficult to lay just take your time getting the folds and wrinkles out.

Dats a very big hose. Check with your local pond center. There are all sorts of sizes and adapters. I wonder if there is a good online supplier? Probably. ebay may be another source for strange sizes.
 
Have a look at some of the koi places (cotswold koi, Blackburn etc) they have a lot of pond piping connectors.

54.6mm is 2” iirc so you may find a matching hose.
 
If it's imperial then the diameter is inner diameter, for metric the quoted diameter is outside. So it's likely that the internal diameter matches the imperial 2".. If the pipe is underground use cemented pipework, seals leak as they age.

Your not alone in thinking the pipework is messed up.. I see that's an ABS pipe too.. so it'll be a pain to chemically join.. UPVC.

My 110mm filter pipework..

These guys may be able to help - they have a lots of connectors etc and I've ordered so they're legit :)

thanks guys long story short im lookin to sort the pond out over the easter weekend

if I can't manage to fix the waterfall I was thinking about temporarily putting some flexible pond hose on the filter but then I have seen the cost for 2 x 10 metre runs and got put off! lol

Flow! Long runs and narrow pipes end up with low flow rates. Also if you start tight or lots of bends so keep them down to a minimum.

You're not the only one, starting Thursday I will be continuing the pond after the winter .. the solvent will mess up under 5 degC so I had to wait.
 
Ok absolute nightmare

lovely pond built in 1989
4m x 5m
Nice waterfall on the top
Someone somewhere spent a lot of money


thought the pond hose was 40mm
Ordered pond hose
It did not match the existing pipe work


So got 38mm hose
Had a few places to join the new hose to the old old
Absoultely a nightmare lots of leaks

the old pipe is rigid so hard and fragile it breaks easily
The new pipe bends at all silly angles lol

I got a few links when joining the old pipe to the new one
Any tips? Silicone? Tape? What do u all reckon?
 
Few leaks ftw

i was thinking silicone wait a day then restart the pump

someone quoted me 4k to fix all of this
Been a tough time
