Fit the lower-delivery pump, then strip and clean the old one and apply Loctite SI 5926.It's a silicon based sealant, so flexible. Did the trick for mine. The old pump is back on, and the new one sits in its box, waiting for the next time. Two years on and counting.
Got some CT1, will give it a go with that, cheers. Shot to nothing, I guess. Have confirmed sighting of weeping so will apply a thin bead all around.
I wonder why the pump design doesn't use a replaceable gasket?

Just give it a try and see what happens. You might need to adjust the accumulator pressure if the cut in pressure of the new pump is different.
The benefit of jabsco (Parmax) pumps is that the pipe fittings push in and a slide on the pump locks them in position so it literally takes 2 mins to change a pump over.
As I've just found; what an excellent design.

I'd recommend that you go back and have a look at what's under the floor as @BWM suggested. That's what I did on mine; Alhough the ballast wasn't 'untidy' with space that could be exploited, it was tightly packed paving slabs which I replaced with denser steel, allowing me to drop the floor by 3" (like BWM, to the keelson).
Taking up the floor and ballast was something that I had to do anyway, to get to the hull floor which needed treating after years of neglect. If your boat is old, and you intend to keep it for any significant time, it's something worth considering while you have the opportunity.

Do you have an onboard shower, and how much water does it use?
(see how long it takes to fill up a known size container at your normal shower setting)
If the pump can't keep up with the demand, the shower water flow rate will drop off after a short time.
Yes, I do have a shower - don't know how to answer that question without measuring - which I can't do right now - but it's just me onboard, and I'm fairly economical. Shower is normally on/off, though rather than setting a desired flow. As long as I'm not doing any harm, that was my main concern. If it's not up to the job, at least it'll do as a stopgap as @ditchcrawler says.

If the OP has an instant gas water heater, the lower flow rate MIGHT cause the burner to shut down, I think.
Should have mentioned, thanks - no gas water heater installed.
I didn't understand what you meant by the pump cycling - would you explain, please?

Hi,
My water pump needs replacing (started leaking), and it just so happens that I have a replacement to hand (gifted, as new).
Unfortunately, I notice that it's a model with a much lower flow rate. Jabsco PAR-MAX 1.9, whereas the old one was a 2.9, so replacing one capable of pumping 2.9 gallons/minute with a new one doing 1.9 gallons/minute.
Everything else appears to be the same (electrically), so am I just looking at the pump running for longer to repressurise?
Cheers!

Don't see why not, it's not particularly aggressive stuff so unlikely to attack toilet plastic (which in my case is a PVC, but mine isn't a Thetford), it's pretty good on white fenders too
Good to know. Cheers!

Has anyone tried this? Aldi are punting out bottles of uPVC restorer for windows, and I thought it could brighten up the plastic exterior of my Thetford cassette set-up.

The Knack? That was *Ray* Brooks
The other thing I was going to mention: that set of slats - scavenged from an IKEA Bodo, just the right width.
-
If you have a mattress 120cm wide, I found that a cover for duvets 140-150cm will fit right over the mattress provided the opening is full or near full width.
Much easier than tucking in a flat sheet, especially if the bed base is built-in with furniture to the sides, and turning the mattress over is a doddle.

And VAT, probably.
Money up in smoke.
Oops, forgot notes are plastic now.

If you think that's horribly expensive, then you shouldn't look at the Halibut.
And that would before you factor in currency exchange charges and import duty from the US
On second thoughts having checked out the link to the 'Bubble 1 Pie Pod' (you what?), perhaps the Salamander isn't *that* bad.
-
Salamander Stoves do a range which seems to tick all your boxes - unless one of those boxes is not being horribly expensive.

Thanks all.
Would a 'swan neck' be a configuration of the hose, something like this:

Or a specific component?

Morning,
Leisurely Sunday morning planning for a new shower install, waste handling in particular. Nearest skin fitting is approx 6 feet distant from shower waste.
No constraints on space or previous install considerations, so what are my options?
Would it be better to have integrated tank/pump or separate?
Would I just need an isolating valve between the shower and tank?
I notice that some tanks have see-through top covers. How useful are these?
Appreciate your thoughts...
-
You could maybe perk it up with border tiles in a contrasting colour, using heat-resistant tile adhesive to stick down on the outer edge of the slabs. Minimal cost/effort.

Anyone know what the situation on Thorpe Island is now?
Jenner's Basin now under new ownership and the basin cleared of boats - likewise for the rest of the island?

I've checked my email, and haven't received this communication from CaRT.
I did however, receive an invitation to take part in a similar consultation last year - the timetable for which was:
QuoteThe timetable is as follows:
October 2020 – January 2021: Engage stakeholders on their views as to how the Trust can best manage the London waterways where we have high demand
January 2021: Following stakeholder engagement the Trust will publish proposals on additional measures to manage the areas of high demand
February - April 2021: Formal consultation with boaters and other stakeholders
May 2021: Review consultation findings and finalize proposals
June 2021: Publish final proposals
July 2021: Implement mooring zone proposals
I haven't received any follow-up communication of any proposals published in 2021, either.

Weighing the two up. Would anyone care to comment on these?

I need to do something related before too long, but I want it to stick directly to steel (under the cants). As you have a gun maybe you could do a few experiments and let us know what you find out?
...........Dave
Sorry it's taken so long to get back to you; 1) about a good half an hour to go touch dry / stiff 2) yes, it'll stick, but the trick is to get it to stay in place initially while it cures. Careful, slow, progressive application might get you there.
-
I wonder if vinyl tape might be an effective solution.

Don't forget if you are operating any boat other than for private pleasure you need either an MCA Boatmaster licence (with a tug endorsement if towing), or an approved licence such as the RYA Helmsman's certificate if the vessel is less than 23 metres in length. There are some exceptions but I don't think any would apply here.

Thank you

The Soudal foam that you're referring to ('Genius' - isn't that the name of the gun system?) appears to be 'resistant to water', according to their website.
Having just used an expanding foam (a different Soudal product), I think that you'll definitely be better off with a gun rather than a tube applicator. You'll likely need to modulate the flow in order to get it to fill the gap and not just shoot down to the bottom of the void. Not sure how you'd tackle the top of the porthole, though. May be tricky.
-
What licences, insurances, etc. would you need to operate a tug (construction, general towing services) on the inland waterways? Appreciate insight if you've relevant experience, TIA

Okay folks, I'll try a light misting. Cheers

That's what I did, missed your reply while I was working on the pump so I reassembled while the sealant was wet. Seems to be working...so far!
