I am trying to replace the hose that goes from my tanks to the macerator pump. I bought this hose: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

Due to the way macerators work, there is always some residual fluid in the hose after pumping. The connections are with hose clamps at either end. For some reason, even after tightening the clamps down they still leak from the ends. Is there any way to get these to stop leaking at the hose clamp area? Thanks.

The problem with this type of hose is the wire coil running through the plastic.

You can try to wrap the pipe with a few wraps of electrical tape before installing the hose. Also spread the coils under the clamp so only one section of wire runs under the clamp. The tape should form a seal around the wire.

Regards,

Maligator....... I assume your leak difficulty happens where you have to clamp the slinky onto the bayonet fittings that allow you to make the twist connection to your tank drain on one end and the macerator on the other. If this is the case you can eliminate the problem by avoiding the cheap slinky hose and buying a higher quality hose, such as Rhinoflex or the Valterra Dominator. These hoses have factory attached bayonet fittings that do not leak and do not come off.

Here is something I found that works well. There is a tape out there that you may already have (sold at RV shows) called Rescue Tape. It's used for all types pf repairs, especially fixing leaking radiator hoses in an emergency. It's a silicone tape that seals to itself as you wrap it around whatever you're repairing.

If you don't already have some, here it is on Amazon. https://www.amazon.com/RESCUE-Self-F...rds=rescuetape

Use the Rescue tape as a gasket. Wrap it around the fitting a few times and then install your sewer hose over it. It's pliable and thick enough to create a seal between the hose and fitting.

I used clear silicon generously around the clean dry fitting. Installed the hose and clamped it. Wiped off the excess and set in the sun to dry.
Solid seal and durable for a long time.

Thanks guys. I will try some of the suggestions. This hose is not from the RV to the dump station. It is a permanent slinky hose that goes from the tank valve to the macerator pump. I don't know why they couldn't have plumbed it hard instead of a flexible hose connect!

What's the distance from the tank valve to the macerator? Could you plumb it hard yourself?

I thought of that but the only way to connect it to the pump is by slipping a hose over it and clamping. It's a crappy design. Pun intended.

It's a 3" outlet, right? Couldn't just pick up some standard pipe and fittings at HD and glue it up yourself?? Or am I missing something?

My inlet to the Macerator, the stiff 3" slinky, had to bend a 90 degree to attach to the y pipe. This 90 degree bend actually broke off one of the ears from my y pipe, so I had to replace that pipe, and replaced the valves whiole I was there. But upon reassembly I added a rigid 90 degree clear pipe to the y pipe allowing the macerator to connect straight. No leaks, and I dig the clear 90, it gives you a warm/fuzzy about how clean your tanks are.
