Going to try and fir shower pump!

[sammy296296]

Howdy,


I'm planning to fit a shower pump tomorrow. Fairly handy with electrics so fine on that side.

However my plumbing experience is not non-existent but limited.


I don’t suppose someone would have a look at the first pic attached and let me know what these circled ‘green’ fittings are? I presume they’re some form of push fitting? How would one go about removing them?


Also if you could have a look at the pump in the pic and perhaps give me some guidance on what additional fittings I’ll need to buy to attach the pump to the lines in the first pic.


Thanks for the help! And lets hope I don’t flood the house!


p.s pump is a "Wasp 60" positive head. Also checked and water pressure should be enough to activate.

Shark bite/tectite fittings (need a special tool to disassemble)

Also the pump needs its own supply from both the cold water tank (lower than the hot water cylinder take off) and hot water cylinder (via an s flange)

Also that pump looks like it's had its day

Sorry to say

Hi thanks for your reply.

The pump is being given to me for free and has been removed perfectly work so not too worried

Thanks, im aware of the 2 inlets and outlets for cold/hot.

Could not cut the pipe and remove 'shark/bite fittings with a pliers?
And then replace with fittings that would mate with the pump? If so what fittings should I use to replace.

Thanks again!

Don't think so


And you would need to run dedicated feeds from both the hot water cylinder and cold water tank

Can't use the hot and cold services to let's say a bath

Thanks,

Yes I will be running dedicated feeds from hot water cylinder and cold from mains feed line. Fyi, on the pic. The pipe in front, with the red circles drawn on it is the hot water line from cylinder and the pipe behind is the cold water mains line.

I suppose I could leave the shark bite fittings in place and cut a chunk out of the middle of the pipe between the red circles and hope I have enough pipe left to attach the pump hot water inlet and outlet between existing fittings??

Thanks again

I'd be more worried about the electrics than the plumbing. No such thing as being 'handy', especially for this sort of thing.

Two things
1- You cannot connect a power pump to the mains feed as it will pop, it has to be from the tank in the loft. (If it is big enough)
2- if you connect the hot side of the pump as above you will be pumping the whole house unless that feed is just for the shower?

It won't be free if you install it incorrectly and flood your house.

Why do you say that?

Hi,

Sorry yeah that is a feed from tank not mains, just comes up under floor..

That hot feed just does shower and kitchen tap.

 

[ShaunCorbs]

Why do you say that?

Looks 6-8 years old and a cheap pump

Grundfos Watermill Wasp46, not a cheap pump in it`s day, depending on history could be good for a few years yet. Only 1.4bar though.

just get a plumber in mate....seriously

 

[king of pipes]

A little knowledge can be dangerous sammy serously bud get a plumber in to sort out spaghetti juction before adding more pipework and the shower pump , you will kick yourself if it goes **** up cheers kop .

 

[sammy296296]

Thanks for all the good advice.

So, the pump is installed, no floods, no-one was electrocuted and no laws were broken. There is now high-pressure water to the shower and kitchen sink! Delighted.

(installed the pump in a slightly different place and left all the shark-bite fittings in place and just added new compression fittings as that's what i'm used to, no leaks!)

Not really the way it should be done sammy but if your satisfied. cant see any valves anywhere if you get a failure it will be costly best of luck kop.

There are valves to shutoff both the hot and cold feed.

Doesn`t that pump sound noisy like that and there is supposed to be air gap under the motor hence use of the feet.
